In order to optimize the speed-control performance of the permanent-magnet synchronous motor (PMSM) system with different disturbances and uncertainties, a nonlinear speed-control algorithm for the PMSM servo systems using sliding-mode control (SMC) and load torque compensation techniques is developed in this paper. A SMC strategy is designed based on field oriented control (FOC) theory, which is...
The drive performance of permanent magnet synchronous motor (PMSM) can be deteriorated due to various disturbances. In this paper, the problem of speed control for a PMSM system with parameter uncertainties is investigated. A new control algorithm based on nonsingular terminal sliding mode control (NTSMC) is proposed, where the controller is developed for speed regulation. Compared with conventional...
A novel simplified stator flux oriented control (SFOC) for three-level inverter-fed induction motor drive is proposed to achieve high performance torque control in both steady state and transient conditions. Sliding mode control (SMC) is designed, in stead of conventional PI controller, to obtain the continuous commanding voltage vectors. The speed accuracy and dynamic tracking performance, as well...
