Method and system for controlling motor torque |
摘要 |
A method and system for controlling motor torque provides improved responsiveness and reliability in motor control applications. The motor control system includes a power converter, a voltage detector for detecting the converter input voltage and a control circuit for controlling the converter. The control circuit includes a torque command limit value generator and a torque command limiter for limiting a torque command value. The system may also include a torque command coefficient generator for generating a coefficient corresponding to an input current of the power converter, and a multiplier for calculating a final torque command value for the motor by multiplying together the torque command value and the torque command coefficient. The torque command limit and coefficient values may be determined from the converter input voltage, calculated or detected converter input current and calculated input impedance between a power supply and the converter.
