Intelligent fractional-order integral sliding mode control for PMSM based on an improved cascade observer Research Articles

Lingfei XIAO, Leiming MA, Xinhao HUANG,lfxiao@nuaa.edu.cn

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 2,   Pages 328-338 doi: 10.1631/FITEE.2000317

Abstract: In this paper, an intelligent control (FOISMC) strategy based on an improved cascade is proposed. First, an FOISMC strategy is designed to control a . It has good tracking performance, is strongly robust, and can effectively reduce chattering. The proposed FOISMC strategy associates strong points of the integral action (which can eliminate steady-state tracking errors) and the fractional calculus (which is flexible). Second, an improved cascade is proposed to detect the rotor information with a smaller observation error. The proposed combines an adaptive sliding mode and an extended high-gain . In addition, an improved variable-speed grey wolf is designed to enhance controller parameters. The effectiveness of the strategy is tested using simulations and an experiment involving model uncertainty and external disturbance.
