Super-Twisting Sliding Mode Control with Accelerated Gradient Descent Method for Synchronous Reluctance Motor Control System

We propose the new speed and optimal current vector control schemes for synchronous reluctance motors (SynRMs) to achieve fast dynamic response and high efficiency using the super-twisting sliding mode control (STSMC) algorithm and the accelerated gradient descent method (AGDM). Through the experimental testing using the 500WSynRM control system, the proposed STSMC-AGDM scheme shows the better speed control performance and motor efficiency, compared with the conventional proportional-integrator (PI) control with/without AGDM and STSMC without AGDM.
