High-Order Fully Actuated Strict-Feedback System-Based Approach for Modeling and Tracking Control of Linear Switched Reluctance Machine

Linear switched reluctance machine (LSRM) is gaining attention in precision motion control applications due to its simple structure and high reliability. This study aims to achieve high-accuracy trajectory tracking for LSRM through refined dynamic modeling and control design. The LSRM is modeled from a low-order physical system to a high-order strict-feedback system (HOSFS), finally transforming into a high-order fully actuated (HOFA) model. A recursive controller is designed using parametric configuration to shape the closed-loop dynamics. Simulation results validate the proposed method's effectiveness in delivering high-performance tracking control for LSRM, specifically in accurately tracking harmonic signals.
