This paper presents an implementation of direct torque control(DTC) of Reluctance Synchronous Motor(RSM) with an efficiency optimization using the 32M DSP TMS320C31<br/> The influence of iron loss can not neglected as high speed and precision torque control of RSM, so the optimal current ration between torque current and exiting current analytically derived to drive RSM at maximum efficiency. For RSM, torque dynamics can be maintained even with controlling the flux level because the generated torque is directly proportional to the stator current The experimental results for an RSM are presented to validate the applicability of the proposed method The developed control system is shown high efficiency features with l.0Kw RSM having 257 ratio of d/q reluctance.
