A composite sliding mode field-oriented control (FOC) for linear induction motors (LIM) is developed in this paper. A new sliding-mode observer-controller scheme is designed to provide a line speed tracking, in which the observer can estimate the load thrust and feed back to controller for small switching gain of sliding mode controller. The control scheme also incorporates super-twisting sliding...
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...
