摘要：

In the surface-mounted permanent magnet linear synchronous motor (SPMLSM) system, the parameter mismatches have deteriorated the control performance of the conventional deadbeat-based predictive current control. In order to solve this problem, a fast terminal sliding mode disturbance observer-based robust deadbeat predictive current control (FTDO-DPCC) is proposed. Firstly, a traditional deadbeat-based predictive current control was derived on the basis of the conventional SPMLSM model, and its robustness was analyzed by considering the parameter mismatches. Secondly, an extended SPMLSM model was given by incorporating the lumped disturbances into one disturbance part. Thirdly, a fast terminal sliding mode disturbance observer (FTSMDO) was designed to track the lumped disturbances fast and accurately. Thus, the extended SPMLSM model was compensated at each control period. Finally, an FTDO-DPCC was designed by minimizing the exponential reaching cost function. Experiments were carried out on a field-programmable gate array (FPGA) based drive system, and the results validate the excellent performances of the proposed method. © 2023 Editorial Department of Electric Machines and Control.
