Abstract
A model-free control strategy for the permanent magnet synchronous linear motor (PMSLM) velocity based on supertwisting sliding mode observer is proposed. Firstly, an ultra-local model of PMSLM at the time of parameter disturbance is established. Secondly, the design speed loop has model-free super-twisting sliding mode feedback controller; At the same time, the super-twisting sliding mode disturbance observation is used to estimate the indefinite part of the ultralocal model. Finally, the feasibility of the PMSLM velocity model-free super-twisting sliding mode control strategy based on super-twisting sliding mode observer is verified in the MATLAB/Simulink platform.
