Design of Model-Free Speed Regulation System for Permanent Magnet Synchronous Linear Motor Based on Adaptive Observer

To simplify the system structure of permanent magnet synchronous linear motor (PMSLM), optimize kinematic performance control system, and further improve speed tracking accuracy PMSLM, a model-free regulation design PMSLM based on adaptive observer is proposed. Aiming at instability problem caused by parameter uncertainty PI in controller (MFC) ultra-local model proposed, which has strong robustness to parameters. Meanwhile, actual used build reference observer, adjustable designed with current equation identify PMSLM. The not only reduces dependence parameters, but also simplifies complexity cost improves anti-interference ability system. MFC (MRAS) are built simulation software applied verify superiority Compared controller, sliding mode (SMC), (SMO), this method structure, speed, dynamic response PMSM optimizes
