A nonlinear speed controller for permanent magnet synchronous motor (PMSM) was designed to achieve speed tracing control and robust adaptive control. The proposed strategy was composed of nominal model method, backstepping control, sliding mode approach and RBF network approach. The controller included two parts: the model controller and the robust controller. The former was designed to ensure a desired...
We consider field-oriented speed control of induction motors without mechanical sensors. We augment the traditional approach with a flux observer and derive a sixth-order nonlinear model that takes into consideration the error in flux estimation. A high-gain speed observer is included to estimate the speed from field-oriented currents and voltages. The observer design is independent of the feedback...
The induction motor speed control systems with multi-variable, nonlinear and strong coupled is considered. The modeled system is divided into two second-order nonlinear subsystems including the angular speed subsystem and the rotor flux linkage one. The non-singular terminal sliding mode (NTSM) control scheme with finite time convergence is used to the design of the controller. The global stability...
