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 a...

| description | 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. |
