This paper presents a rotor position estimated method of a five-phase IPM motor based on high-frequency sinusoidal voltage injection to improve the sensorless control system performance at low speed for electric vehicles. The high-frequency sinusoidal voltage is injected into the estimated rotor reference frame. The estimated rotor position and speed are obtained by detecting and processing high-frequency...
A hybrid predictive control strategy is proposed which can efficiently deal with the speed regulation control of permanent magnet synchronous generator (PMSG) in wind-energy conversion system. A single linear MPC controller is designed with a simpler linearization model. Model predictive controller generates control voltages which are iuput into PWM controller. Thus PMSG can be controlled by three-phase...
In this paper, a novel adaptive height and attitude controller for a small-scale unmanned helicopter is proposed to deal with the parametric uncertainty. Firstly, the dynamic model is decoupled to two subsystems and transformed to linear parameter dependent style equivalently. Then, feedback linearization and back-stepping are used to design adaptive controller for height subsystem and attitude subsystem...
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...
