PMLSM position control based on continuous projection adaptive sliding mode controller

Abstract

In this paper, the design of projection-based Adaptive Sliding Mode Controller (ASMC) is presented for position control of Permanent Magnet Linear Synchronous Motor (PMLSM) with unknown mover mass. The PMLSM model was first established and a vector control based on field orientation is used to decouple the cross-coupling in motor model. ASMC has been adopted to deal with the unknown mover mass and to give robust operation against external load thrust. Based on the Lyapunov method, the stability of adaptive sliding mode-controlled PMLSM has been proven and the adaptive law has been developed. Additionally, a continuous projection operator is applied to adaptive law such as to enforce the estimated mover mass within a pre-specified bound. The performance of ASMC based on continuous projection operator is investigated via simulation results within MATLAB environment. Also, a comparison study in ASMC performance is made due to the inclusion continuous and discontinuous projection operators. The simulated results showed that ASMC based on continuous projection gives better performance than that based on discontinuous one.

Design and Comparative Study of Advanced Adaptive Control Schemes for Position Control of Electronic Throttle Valve

“…The integration of SMC strategy with adaptive control theories lead to the emergence of what is called "Adaptive Sliding Mode Control (ASMC)". This combination provides the SMC with the powerful features given by both methodologies, i.e., the robustness characteristics gained by SMC together with the adaptive capability acquired by adaptive control theory to cope with totally unknown parameters [8,9]. Furthermore, combining the features of adaptive sliding mode control with backstepping control acquires the benefits of performance characteristics and robustness of the three strategies and yields so called Adaptive sliding mode backstepping control (ASMBC).…”
