摘要： A hybrid sample rate servo motor employing rate feedback compensation is disclosed. The system employs a shaft encoder (55) having a predetermined resolution to provide position data which are pulses indicating the shaft has moved another resolution unit. Under high motor velocity conditions the rate compensation feedback loop (60) is operated at a conventional constant sample rate. Under low velocity conditions, the sample rate at which the rate compensation feedback loop is operated is modified so that rate samples are taken and calculated only when new position data are available from the motor encoder. Rate quantization error is substantially reduced, thereby leading to more robust controller operation.
