具体实施方式
在以下详细描述中,描述了许多具体细节,以充分理解本公开的各方面和实施方案。然而,对本领域的普通技术人员显而易见的是,本公开的各方面和实施方案可在无需这些具体细节中的某些细节的情况下实施。在其它情况下,为了便于理解,未详细示出所熟知的结构和技术。
应当理解,本公开的上述概述和以下详细描述均为示例性和解释性的,而不旨在限制本公开的范围。此外,关于本文中使用的术语,除非特别说明,否则对单数形式的元件的引用,并不旨在意指“一个且只有一个”,而是“一个或多个”。术语“一些”是指一个或多个。下划线和/或斜体标题和副标题的使用仅为了方便起见,而不限制本公开,并且并非是指与本公开的说明的解释相关。
本公开的实施方案涉及通过施加具有固定频率和固定持续时间(FFFD)的控制脉冲来向电(包括电子)负载输送或施加功率的控制技术。所述负载可为任何类型的直流负载,但对于不同应用而言,可能需要电路中发生某些变化。此类FFFD技术可提供比先前技术(著名的PWM和VF技术)更精确的功率输送。这种精确的功率输送在许多应用中是有利的,通常是在电负载中,尤其是在电动机、电灯和电热元件中。这种精确功率输送可特别适用于精细作业,例如在假肢、机器人、遥控机械臂(如航天飞机上)以及机动化医疗或手术设备的控制移动中,其中细微的触碰和精确度是至关重要的。需要精确电动机移动的其它应用包括航空器如无人驾驶飞机的控制、天文望远镜的移动以及远距离武器如海军大炮的移动。
根据本公开的FFFD技术包括用于驱动电负载(例如电动机)的设备和/或方法,其可比脉冲宽度调制(PWM)或变频(VF)技术更精确。例如,PWM改变共2个可变控制参数:(1)脉冲宽度和(2)总周期长度。VF改变共2个可变控制参数:(1)脉冲长度和(2)这些脉冲的频率。通过使用FFFD技术,可使设计者改变(1)开启脉冲的固定长度、(2)关闭或恢复期间的固定长度、(3)一个周期的总时间周期和/或(4)该时间周期中的脉冲数目。当电动机为电负载时,特别相关的是每个FFFD开启脉冲的功率的精确输送,从而允许精确的电动机移动。因此,根据本公开的FFFD技术可有利地代替PWM和/或VF技术使用。
图1A示出了根据本公开的示例性实施方案的简化电路示意图,其示出了FFFD功率控制的通用技术(系统和/或方法)100。如图所示,直流负载106可连接至所提供的从正电压轨105流向负电压轨110的电流,并且可通过该电流来供电。电源开关107可中断该电流,或使其不间断地通过,如控制脉冲108所命令。脉冲串108的模式和有效占空比最终决定通过负载106的有效电流,但该电流的准确度、效率和有效性则取决于该脉冲串的具体模式,如以下说明所描述。如果电源开关107为功率场效应晶体管(FET)装置,则脉冲串108(或G脉冲)将被施加至FET的闸极。在其它构造中,可使用任何类型的电源开关装置,诸如晶体管。
图1B示出了简化电路示意图100B,其示出了非电阻性负载可能需要的一些不同的构造。与图1A相比,图1B示出了两个开关元件115和125。通过使用针对两个开关的G脉冲串130,此双开关可将负载120与V正线和V负线完全隔离。这在例如当负载120在本质上具有高度电感性(例如使用电动机)时可能是必要的。当将电感负载切换成关闭状态时,感应电流将导致负载120的负端出现电压尖峰,因此在该情况下,可能需要旁路二极管140将此电流钳位至合理的电压。同样地,如果需要负载120具有非常精确的功率值,例如希望将关闭状态切换至尽可能接近零,则分流电阻器150将有效地分流走流经呈关闭状态的切换装置115的漏电流。
在图1B所示的实例中,可看出当切换为关闭时,负载120真正地呈零电流状态,而在图1A中,在关闭状态期间,负载106可持续使开关107的漏电流流动经过。显然,使用FFFD技术的其它电路设计可能仅包括这些额外组件的一些,或甚至更多且不同的组件,这对于那些特定电路设计的单位负载的变化与所需性能而言可能是需要的。
应理解,可用根据本公开的FFFD技术替代PWM和/或VF技术。通过FFFD技术来施加功率的电负载实际上是需要对供给功率进行控制的任何类型的元件或组件。施加至负载的功率可通过改变在重复时间周期内的FFFD脉冲数目进行控制。例如,此类负载包括但不限于以下任一种:电气或电动动力工具、任何种类的电气照明(例如LED阵列、高强度放电(HID)照明等)、电热器和加热元件、风扇电动机和空气净化器、电动自行车、摩托车、小型摩托车、电动高尔夫球车、电子玩具、电动舵机、电动船、电动液压系统(包括它们在起重机、手推车、手动拖板车中的应用)、电子或电动假肢、电子或电动义肢、电动牙刷、电子或电动医疗设备(包括可调床、轮椅、吸引设备、人工心脏、牙钻)、电动泵、电子和电动无人驾驶飞机、电动训练设备(包括跑步机、爬梯机)、电动车(包括公交车、火车、室内有轨电车、手推车、地铁)、电器(包括电冰箱)、电动园艺工具(包括剪修工具、杂草切除机、绿篱机、割草机)。示例性实施方案可与无刷直流电动机一起使用,包括用于线性和旋转式致动器或伺服电动机的那些。
图2示出了根据本公开的示例性实施方案的一组定时图,其示出了FFFD方法的基本构思。如图所示,单个G脉冲201可开启电源开关,例如图1A中的电源开关107,以用于等于基本脉冲长度的短周期。这将一组数量的功率提供至负载,例如图1A的负载106。例如,如果需要将三倍(3X)功率输送至负载,则通过脉冲控制串(例如图1A的脉冲串108)来对三个(3)脉冲205进行时控。这些脉冲(例如图1A脉冲串108所示的脉冲)可通过具有逻辑输出的微型计算机或其它类似装置(例如,处理器系统,如CPU等)的输出来形成。同样地,如果说需要六倍(6X)功率,则将六个(6)脉冲发送至电源开关,例如图1A的电源开关107。此模式可在长度周期(或周期)Tcycle 211中重复,可将Tcycle 211选择为足够短到不会在负载(例如图1A的负载106)中引起问题,但却足够长到允许负载所需要的最大所需脉冲108。如果Tcycle(定时循环周期)过长,则施加至负载的功率可能似乎不均匀,即不规则。
继续参考图2,Tcycle 211优选地足够长以具有足够的脉冲数目来进行精细控制。例如,如果在功率步骤中需要使负载控制在1%之内,则Tcycle211将优选地包括周期类型210的长度那样长的至少100个脉冲数。然后,Tcycle的确定将取决于以下应用,即特定负载(例如图1A的负载106)的具体要求。如果负载例如为LED光,则脉冲210每者均可为一微秒的若干分之一,并且Tcycle 211为一毫秒的若干分之一。如果负载(例如负载106)为汽车的电动机,则根据设计细节,脉冲210可例如为20毫秒,并且Tcycle211可例如为250毫秒。
图3示出了定时图的集合300,其示出了本公开的FFFD实施方案与脉冲宽度调制(PWM)和变频(VF)的常规功率控制方法之间的区别。在PWM中,脉冲301显示最小时间周期的脉冲。如图所示,当需要三倍(3X)的功率量时,脉冲长度305会长于三倍(3X)。理想的是,脉冲305将产生的功率为脉冲301的数倍(3X)。如随后所示,这仅为理想情况;而不会在实际电路中发生。脉冲流310显示了在VF方法中用于提供1级功率的特定脉冲重复频率。为了提供三倍(3X)的功率,需要三倍(3X)的频率,以产生脉冲流315。另外,在理想情况中,这应当提供数倍(3X)的功率,但在实际电路应用中这将被显示为具有偏差。
图4示出了定时图的集合400,其示出了PWM技术的缺点。图4示出了PWM方法在实际电路中不准确的原因。假设脉冲401为PWM应用中的最低功率状态的脉冲。这会产生通常被示为410的电流。虽然理想的是,该电流应为方波函数,即与控制脉冲401相同的形状,但是真实情况则具有电容与电感效果。这甚至在负载为纯电阻性负载时也是如此,因为连接电路必须具有有限长度的导体,而该导体又必须具有可测量的杂散电容和电感。因此,电流410的典型波形由于这些非零的电容值和电感值而表现出失真。该上升时间和“环形”波形可通过将示波器探针连接至典型电路而容易被看见。这种环形对PWM方法具有影响。然后,由脉冲401产生的总电流由图线415表示。如果脉冲420表示PWM实例的2级PWM脉冲,则脉冲420尽可能接近脉冲401长度的两倍。该结果为由图线430所示的电流。另外,在理想情况下,430的形状应当为与控制脉冲420相同的形状,并且理想的是,430的总电流正好为电流410的两倍。在实际电路中,图线430为实际电流的典型图示。由于410与430为环形,则总电流435不为415的总合的两倍,而是某个其它值(其实例如图6所示)。
图5示出了FFFD方法如何更精确地产生功率的增量。在FFFD脉冲501中,对负载所产生的瞬时电流由实际的典型波形505来显示。这可产生曲线510所示的总电流。当需要两倍的功率值时,FFFD方法采用两个脉冲,如520所表示。因为这两个脉冲大致相同,并且每者均与501具有相同的形状和长度,所以所得瞬时电流525仅为两个大致相同的波形525,这些波形中每者均与505大致相同。因此,由两个FFFD脉冲520产生的总电流530为510的电流(针对单个脉冲501)的大致两倍。即使对于实际电路,两个脉冲520也可通过明显的环形来提供一个脉冲501的功率的大致两倍,如图所示。
图6包括定时图的集合600,其示出了PWM技术的缺点。在图6中,曲线640表示PWM脉冲时间,其需为单个时间周期的功率的11倍。在理想情况下,曲线650上所显示的所得电流包1至11将在时间、大小和形状上相同,特别地完全为矩形。然而,在实际电子电路中,电感和电容以及控制电子流速度的物理定律会产生由曲线601表示的所得电流的实际波形。在该波形上,能够看出,该波的第一部分由于电子器件的电感效应而在605处呈现上升时间。如610所示,相同的电感会使电流过冲而达到高于理想的纯电阻情况中所遇到的水平。然后,电流会在该曲线的615至611处经历一个周期或环形,直到最终稳定到一个稳定值,而这在PWM脉冲相比于最大总环形时间而言较短的情况下绝不会发生。PWM脉冲的每个时间周期的所得电流包由曲线620表示。如图所示,第一时间包621小于第二包622,并且每者均不同于所有其它包,直到环形最终停止为止,但可能不会在与第一脉冲相同的值处。即使当PWM脉冲停止时,实际的电流切断也会产生由630表示的电流。因此,PWM方法不能仅通过将时间周期延长多倍量来提供多倍单个脉冲。该实例仅显示了PWM方法的电流侧。当考虑到功率的无功分量和功率因数(即瞬间电压×瞬间电流)时,与理想情况的偏差甚至会更加失真。因此,不可实现通过PWM对精确值的控制。
图7包括与本公开的FFFD实施方案相对应的定时波形的集合700。图7示出了FFFD脉冲如何不会受到实际电路的环形的影响。对于短FFFD脉冲而言,曲线705为当电路从关闭状态切换至开启状态时的电位波形(相当于601的上升时间和环形),并且曲线701示出了通过电路的实际电流,以上升时间失真完成,并关闭在后沿处的泄漏。总电流包由710表示,其包括上升时间、环形和关闭失真全部,但在第一脉冲的基本周期结束时截止。当向电源开关提供多个FFFD脉冲时,其结果为被示为715的多个电流包。每个715电流包均与单个包701大致相同。FFFD脉冲之间的弛豫时间717使得实际电路在第一脉冲之前回到初始状态。这意味着每个脉冲715具有与向脉冲705提供的大致相同的起始状态。
因此,通过仅仅增加脉冲数目,根据本公开的FFFD技术便可产生功率的任何整数增量。一个限制因素可为功率增量的最大分辨率必须适合Tcycle时间周期,例如图2的周期211,并且在采用FFFD方法时,这些数目被选择作为设计周期的一部分。
固定持续时间脉冲在FFFD中的优点可能也适用于变频(VF)方法(图310、315),但事实并非如此,如下面将解释。虽然VF方法中的所有脉冲的开启周期相同,但是该方法存在若干缺点。由于数字计算机的数字特性,通过其来完全产生所有频率是不可能的。例如,如果将1000赫兹用作所需功率的最低值的基准频率,并且其可以每1.0毫秒在一个脉冲中产生,则对于3的值为3千赫兹或333.333333赫兹,其不能在数字上确切地实现。考虑到该问题将针对至少每个质数发生,并且数值“粒度”将在较短的时间周期时存在更大的问题,因为脉冲更紧密地在一起,即性能系统更高。同样考虑到在图315中,脉冲之间的时间会随着频率的每次变化而改变。这意味着弛豫时间(即关闭时间)会随着每个不同频率值而改变。因此,对于每个频率而言,初始状态均不同,因为这些脉冲之间已存在不同量的稳定时间。另外,例如对于高性能系统而言,当脉冲之间的时间变短时,该问题将是最普遍的。FFFD技术通过使频率和脉冲开启周期保持恒定可确保功率增量尽可能接近理论数值。
此外,FFFD技术可提供优于VF技术的另一个优点。例如,对于FFFD技术,脉冲计时是恒定的,并且可被选择以使得在敏感频率上无射频干扰(RFI)。相比之下,对于VF,这些频率不同且以多个频率及其谐波辐射,这可导致不必要的RFI。这对于诸如对航空器和医院等的应用尤其如此,其中RFI可导致严重的问题。这些情况下的VF可能需要屏蔽RFI,然而一旦设置了FFFD计时,则任何RFI均具有固定频率,由此具有可预测的频率。这种RFI问题尤其出现在将脉冲用于驱动电动机的情况下,因为电动机绕组对功率的固有使用会使磁场形成和崩溃。
根据本公开的FFFD技术可在其它方面具有明显的优点。以其在驱动电动机上的用途为例。标题为"Current Limiting For Electric Motor Start-up"的美国专利第5,442,272号教导到,需要具有附加外部组件,以在从停止状态启动直流电动机时,防止过电流流动。然而,通过使用FFFD方法,可选择脉冲持续时间,以提供在电动机停止且没有反电动势时不会超速驱动电动机绕组的脉冲功率周期。这也可防止电动机上的机械负载大到使电动机移动停止时的过电流状况,并且可选择脉冲持续时间和间隔以便不使绕组过热。对于PWM,试图补偿过载电动机的控制器可将占空比的长度增加至会损坏相关电动机的长度;FFFD技术则可防止这种情况发生。
大多数电子器件由使用数字电路的计算机控制。由于计算机的数字特性,FFFD方法比PWM或VF更适于计算机应用。计算机与置位时钟一起运行,这意味着计算机指令的执行(即运行软件)仅发生在计算机时钟周期的特定部分处。通常,计算机时钟在机器语言指令集中的多个上运行。
注意图8,示出了根据本公开的示例性实施方案的波形的集合800,其示出了计算机或处理器所产生的G FFFD脉冲的定时信号。
在图8中,计算机时钟信号被示为信号810。在典型的计算机芯片中,计算机机器指令的“执行”部分(通常为整个计算机周期中的四个部分之一)通常以每第四个时钟周期发生,(虽然一些特殊类型的计算机机器指令可能会变化,但其仍是偶数个时钟周期)。这意味着,如果计算机试图在输出端口上产生高、然后低、然后高状态的脉冲周期,则这些状态变化可能仅在以每第4个周期来表示的离散时间发生(如图8中以820来表示),并且以线条830所表示的离散时间标记再发生。因此,最快的脉冲将为由四(4)个时钟周期组成的脉冲,如840所示。
继续参考图8,对于一个计算机指令将线条设置为较高(在840处)的情况,将输出端口复位至较低可能最早仅发生在845或任何其它时间标记830处,而非两者间的任何时间。例如,图8上的高周期860表示三(3)个全计算机定时循环的脉冲。全计算机周期之间的脉冲(例如2.7)由于计算机的固有操作而不可能存在。同样地,脉冲850、875的较低或恢复部分也为计算机循环次数的整数值。在所示实例中,850的关闭或低周期为七(7)个计算机周期那么长,并且对于875而言,其为九(9)个计算机周期那么长。一旦这两个周期,即高状态周期840或860以及低状态周期850、875由FFFD电子电路的用户来选择,则这两个周期由于计算机操作的性质而被简洁地复制。为此,计算机的输出端口仅可在离散时间830处从一种状态切换成另一种状态,并且控制电动机或其它电负载的功率的VF方法为何不精确的原因变得显而易见,因为脉冲的一小部分是不可能存在的。
生成由FFFD参数的选择所产生的G脉冲流或串(例如图8的串880)的硬件可通过图9所示的电路在一个实施方案中实现。
如图所示,被指定为CPU的计算机芯片(即元件930)可利用计算机时钟910,例如石英晶体组件,以得到时钟频率920。可以看出,920对CPU提供时钟脉冲,例如图8的脉冲串810,从而在CPU 930运行适当的软件时,使I/O(输入/输出)端口940具有产生G脉冲信号950(类似于图8中的880)的能力。当然,本公开并不受限于特定类型的振荡器或时钟,并且任何合适的类型均可用于本公开的实施方案中。
CPU(例如CPU 930)的软件可在示例性实施方案中包括或执行图10所示的子程序1000。对于子程序1000而言,每当要在每个Tcycle开始时(例如图2的周期211)产生G脉冲流时,该CPU中的主要软件便会调用从1005开始的子程序“G脉冲时钟输出”1000。用户例如在1010处向所述子程序指定要产生的脉冲数目N,高或开启周期的计算机循环周期的长度HI,低或关闭周期的计算机循环周期的长度LO以及必须使用该G脉冲流来驱动的I/O端口的数目S。
所述子程序可确保G脉冲流处于低状态,如1015所述。然后,将计数器设置为等于1010所命令的高周期的数目,例如等于HI。如果需要尽可能最短的脉冲,例如计数等于1,则在计数1035的测试中,该程序会分支到1030,其将I/O端口S设置为高,然后在1060,在恰好下一个计算机周期内将其重新设置为低。如果相反地在指令1035中,指定的计数大于1,则将I/O端口S设置为高1040,并且通过使指令1055经由1050分支到其本身来将计算机周期计数以每个计算机周期递减一个数。每个回路到其本身会消耗一个计算机周期,并且会使计数递减直到最后的周期为止,此时计数等于1,并且该程序继续进行通过将S I/O端口设置为低来终止高状态的指令1060。然后,将计数器设置为G脉冲应当处于低状态时的计算机周期的数目,例如LO。分路1070中的回路回到其本身1080,使计数器每个回路递减一个,直到该值达到零为止。当计数器已对LO数的周期进行递减计数时,该程序继续进行到1085。如果该Tcycle周期的G脉冲的数目为1,则减量到0会使该程序退出子程序1190,直到在下一个Tcycle开始(例如图2的Tcycle 211)时,该程序再次调用该子程序为止。如果脉冲数目大于1,则减量N会产生非零值,并且子程序分支1075回到1025,其中会产生下一个高脉冲。当该Tcycle的G脉冲数目完成时,N计数将为0,并且子程序将退出1085而进行至1090。
该子程序的结果为G脉冲流,例如图8的880,其中对于顶部模式而言,HI=1,LO=7且N=3(如图所示);并对于底部模式而言,HI=3,LO=9且N=2(如图所示)。需要注意的是,Tcycle(例如图2的Tcycle 211)将远长于图8所示的时间周期,因此该数目N会远高于图8单独所示的数目。
FFFD技术可在各个其它实施方案中具有由模拟分量而非数字分量所产生的多个FFFD脉冲(“G脉冲”),如关于图11来示例性说明。
图11示出了根据本公开的示例性实施方案的用于产生FFFD脉冲的模拟电路1100的电路示意图。在图11中,模拟电路1100包括两个单触发(或单发)组件1150和1190(例如CD 4047CMOS装置)或者其在TTL中的等效物或其它固态变型。如图11所示,由该Tcycle时间中的G脉冲所产生的脉冲数1105被加载到递减计数器1110中。计数器的非零状态使零(逆向)线条变高1115,从而触发单触发组件1190。单触发组件输出由RC网络1120所确定的设定持续时间的脉冲1125。该构造最可用于硬件设计中需固定G脉冲的时间周期的情况中。可例如通过使用RC构造内的微调电位器或调谐电容器来实现对RC时间的调整。脉冲1115通过电路1140反转,从而提供1125的反转脉冲1145的形式。然后,1145的上升边与1125的后沿处于同一时间,并且触发单触发组件1150,单触发组件1150通过RC网络1155来调整,以提供G脉冲的关闭或低时间1160。另外,如果需要,该RC网络可通过微调电位器或调谐电容器进行微调。脉冲1160和脉冲1125与NOR闸极1165组合以提供脉冲1170,如定时图1195所示。脉冲1170用于在引脚“/禁止”(负禁止线)处禁止计数器1110的前进。当脉冲1170完成时,脉冲1170的上升边缘1180允许计数器1110前进到下一个G脉冲。当计数器1110递减计数到零时,其停止将脉冲经由线1115发出到单触发组件1190。G脉冲在此电路中出现在1130处。在Tcycle 211结束时,下一批G脉冲通过以脉冲数目再次加载计数器1110来输出。
因此,本公开实施方案可提供相对于先前技术(包括PWM和VF技术)的有益效果。根据本公开的FFFD技术利用具有固定频率固定持续时间脉冲的电序列脉冲来控制施加至给定电负载的功率。所述负载可为任何类型的直流负载。例如,本公开的实施方案可对例如在假肢、机器人(例如航天飞机上的遥控机械手臂)以及机动医疗或手术设备的精细作业提供精确的功率控制,其中精细触控至关重要。需要精确电动机移动的其它应用包括航空器如无人驾驶飞机的控制、天文望远镜的移动以及远距离武器如海军大炮的移动等。
虽然本文中结合特定实施方案描述了本公开的各个方面,但应该指出的是,适用领域的技术人员可在本公开的精神范围内做出变化。
可在不脱离本公开精神和范围的情况下将本文描述的各种功能和元件与所示出的那些进行不同的划分。对这些实施方案的各种修改对于本领域的技术人员将显而易见,而且本文定义的一般原理可应用于其它实施方案。因此,在不脱离本公开和要求保护的实施方案的精神和范围的情况下,普通技术人员可进行许多改变和修改。
本领域技术人员将理解到,本公开的实施方案和/或实施方案的部分可以/用计算机可读存储介质(例如,硬件、软件、固件或任何此类的组合)来实施,并且可分布在一个或多个网络上。本文描述的步骤,包括推导、得到或计算本公开实施方案所利用和/或产生的公式和/或数学模型的处理函数,可通过一个或多个适合的处理器例如中央处理单元(“CPU”)处理,从执行呈任何合适语言(机器相关或机器独立语言)的合适代码/指令。
