摘要
This paper proposes a novel non-singular terminal sliding mode (NTSM) control approach for permanent-magnet synchronous motor (PMSM) to realize free-chattering sliding mode control with structure of double closed loops. Specially, the dead time and switching delay of inverter is considered, and further an integrated model of PMSM, inverter and mechanical load is established. Then an improved NTSM control method is proposed by utilizing the concept of relative degree, producing advantages of chattering elimination and finite-time convergence at the same time. Besides the controller design of speed loop and current loop by using the proposed method, an auxiliary adaptive control law is combined to overcome unknown uncertainties of inverter. Simulation results are presented to valid the proposed method.
