Abstract:
1. An adaptive motor control system, comprising: an input for receiving a predetermined current command (I an input for receiving a sensed motor shaft angular position (θ); an input for receiving a measured response (y a processor configured to run an adaptive algorithm, wherein said algorithm comprises, an adaptive torque ripple cancellation stage configured to produce a torque ripple cancellation signal (i a model reference adaptive inverse controller configured to produce a current command adjustment to effect a delayed y an active damping feedback control loop configured to produce a damping signal as a function of said measured response; a summation block configured to produce an output current command signal as a function of said current command adjustment, said predetermined current command and said damping signal; wherein said algorithm is configured to cause a motor driven by said output current signal to produce the desired output torque with reduced noise.
