MOTOR CONTROL SYSTEM

A control system for an electric motor comprises a controller which receives as an input a demanded motor current and produces at an output an intermediate voltage demand signal, a voltage demand signal correction means arranged to generate a voltage demand correction signal, and a combining means arranged to combine the intermediate voltage demand signal and the voltage demand correction signal to produce an actual voltage demand signal that is applied to the motor by pulse width modulation of the switches of a motor bridge driver. The correction signal compensates for unwanted non-linearities caused by interlock delays in the switching of the motor bridge switches. 种用于电机的控制系统，包括：用于接收需求电机电流作为输入并在输出处产生中间电压需求信号的控制器，被布置为生成电压需求校正信号的电压需求信号校正装置，以及结合装置，该结合装置被布置为结合中间电压需求信号和电压需求校正信号，以产生通过电机电桥驱动器的开关的脉宽调制施加于电机的实际电压需求信号。校正信号对由在电机电桥开关的开关内的互锁延迟引起的非期望的非线性进行补偿。
