“…Permanent magnet synchronous motor (PMSM) has been extensively used in various servo drive systems owing to their attractive characteristics, such as high-power density, strong driving ability, small size and low moment of inertia. Based on the non-linearity of PMSM, it has been affected by external load disturbance and internal parameter variations in practical applications, so achieving good control results was difficult by the proportion-al-integral (PI) control in both rapidity and immunity [1,2]. In order to improve the performance of PMSM, various non-linear control methods have been proposed, the sliding mode control (SMC) has attracted people's attention for the fast response and robustness.…”

In this study, an improved sliding mode control (ISMC) method combining continuous non-singular terminal sliding mode (CNTSM) and linear active disturbance rejection control (LADRC) for permanent magnet synchronous motor (PMSM) servo system is proposed to improve the performance of PMSM. Based on the mathematical model of PMSM, combined with SMC theory and LADRC theory, CNTSM controller based on continuous function is proposed to solve the singularity of terminal sliding mode (TSM) control. In order to solve the contradiction between the convergence performance of sliding mode control and the ability of chattering suppression, fuzzy control is introduced to adjust the gain of sliding mode controller in real time. LADRC is developed to ensure the current starting conditions of the motor and improve the robustness. Moreover, the asymptotic stability of the system is guaranteed by the Lyapunov theorem and it is verified by the AISim MBD servo motor experimental platform. Experiments show that the algorithm has good tracking performance and robustness.
