Abstract
A motor circuit incorporated into a control system for a motor, in which the motor circuit comprises: a current determination stage arranged to generate a current demand signal in response to a torque demanded of the motor; a feedback loop comprising: a detector stage including a means for determining one or more operational values from the motor; and a current controller configured to calculate an error signal using one or more operational values from the detector stage and the current demand signal from the current determination stage; and a feedforward path comprising: a voltage controller configured to calculate a voltage demand signal from the current demand signal and one or more operational values from the motor, wherein the voltage controller comprises a first bandwidth filter, and wherein the current controller is configured to combine the error signal and the voltage demand signal to produce a signal for the motor.
