A FULLY DIGITAL-CONTROL STRATEGY FOR SYNCHRONOUS RELUCTANCE MOTOR SERVO DRIVES

For existing electric drives, the controller implementation is either totally analog or hybrid analog/digital, and the-control algorithm bro adly falls into two categories, average torque control (ATC) and insta ntaneous torque control (InsTC), In this paper, a fully digital-implem entation-oriented control strategy-incremental torque control (IncTC)- is proposed and verified with digital simulation, A TMS320C30 DSP-base d implementation of the proposed IncTC is developed and tested, Experi mental results given in the paper indicate that the proposed IncTC is valid and holds a great promise for reluctance motor digital control.
