Robust Scalar Control of Synchronous Reluctance Motor With Optimal Efficiency by MTPA Control

In order to achieve improved performance and efficiency of domestic industrial fan/pump applications using low-cost solutions, the synchronous reluctance motors (SynRMs) remains a better choice than induction (IMs) which are still widely used for such despite its low during speed operation. However, due lack self-start capability SynRMs need external drive control algorithm properly operate, increases production cost. For purpose providing cost solutions control, this paper presents stable, reliable robust scalar SynRMs. This strategy implements maximum torque per ampere loop high operation online parameter estimation performance. The proposed solution presented in can be implemented MCU PWM inverter with lower carrier frequency, thereby making SynRM application feasible practical.
