Speed Regulation for PMSM Drives Based on a Novel Sliding Mode Controller

Abstract

This paper develops a novel sliding mode control technology and a comprehensive evaluation methodology for speed control of permanent magnet synchronous motor (PMSM). In most of the existing literature, only control precision of the speed corrector is investigated. However, the control strategy should be stable to the noise and disturbance caused by the environment and parameter uncertainties. In order to possessing faster dynamic response, stronger anti-interference ability and high stability of input, a highly stable sliding surface is proposed for siding mode control. Unlike most of reaching laws that requires the variation of designed sliding surfaces, this method takes state vectors in consideration. In addition, a comprehensive evaluation algorithm is presented to obtain reasonable assessment on speed control for synchronous PMSMs in different operating phases (starting, transient, steady-state rating). Finally, the simulation results verify the effectiveness and validity of the proposed sliding mode speed controller.

Research on a New Adaptive Integral Sliding Mode Controller Based on a Small BLDC

“…Where, equation ( 13) contains the state variable L T of the motor load torque, so the load torque ˆL T obtained by the observer can be substituted into equation (13), and q i can be used as the input u of the control system. Considering the error term between ˆL T and L T , we can get the differential expression of the speed control system state equation of the motor as follows:…”

“…To improve the dynamic performance of the motor, researchers have proposed a series of feasible motor nonlinear control methods, such as neural network control [6], active disturbance rejection control [7], model predictive control [8], [9], fuzzy control [10] and sliding mode variable structure control [11]. Among these control methods, sliding mode control has become an important research field of motor control because of its invariance to the parameter perturbation and external disturbance of the controlled system [12], [13].…”

Hybridized GWO-RUN optimized fractional order control for permanent magnet brush-less dc motor

“…A hysteresis control [10], based on synchronous reference frame also comes into the picture when fast and precise response is needed. The literature review reports that various complex nonlinear control approaches are exerted in designing a controller for the brush-less dc motor drive system, such as fractional order proportional integral derivative (FO-PID) control [11], sliding mode control (SMC) [12,13], adaptive control [14], H-infinity control [15], variable structure control [16], predictive current control [17] and model reference adaptive control (MRAC) [18] . These controls widen the constant torque region which intern improves the speed-torque characteristics of the motor.…”

Adaptive Super-Twisting Sliding Mode Control of Permanent Magnet Synchronous Motor

“…By adopting these ideas, the modified SMC approaches have been successfully applied in many fields. Feng et al [25] proposed a new reaching law, which achieved the expected goal of impairing chattering. e author in [26] used a super-twisting algorithm as the loop of the speed controller to fulfill high performance and attenuate chattering.…”
