Source abstract
Abstract
Purpose This study aims to propose the multiple power nonsingular terminal sliding mode (MPNTSM) to improve the reliability and control performance of permanent magnet synchronous motor. Design/methodology/approach The convergence speed of the sliding mode control is improved, the singular problem of the TSM is solved and trajectory design of the high-performance servo system is performed. To deal with the chattering of sliding mode control, a novel gain of the switching control is proposed, which can reduces the chattering of the machine and improve its lifetime. Findings The novel control method was applied to the permanent magnet synchronous motors speed servo system. Simulation and experimental results show that the MPNTSM can improve the dynamic behaviour and the robustness of the system. Originality/value The chattering problem is weakened so that the reliability of the system is improved.
