In this paper, the adaptive controller is designed for permanent magnet synchronous motor (PMSM). Due to gain the good dynamic performance, the differential action is application in the torque observe equation. Advanced, the controller parameters are optimized by adaptive weighted particle swarm optimization (PSO). The simulation results show that the system with the proposed controller has the robust...
This paper proposes a novel sensorless speed tracking control scheme for the permanent magnet synchronous motors (PMSM) with uncertain parameters. An angular speed observer is designed to achieve the purpose of sensorless speed estimation, and then a speed tracking controller is developed with the adaptive backstepping technique to deal with the parameter uncertainties and load variation in the PMSM...
A nonlinear speed controller design for permanent magnet synchronous motor (PMSM) based on adaptive backstepping technique is presented in this paper. In order to improve the ability of torque estimation, the differential action is application in the torque observe equation. To achieve good dynamic performance and robust, the controller parameters are optimized by adaptive weighted particle swarm...
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...
In this paper, the design of a backstepping adaptive type-2 fuzzy controller for induction machine is addressed. The backstepping has been adopted to exploit the field oriented control scheme and to use only one control channel. Thus, the true and virtual control signals have been synthesised using two adaptive type-2 fuzzy systems to overcome the constraint on the knowledge of the machine parameters...
In this paper a robust nonlinear controller is presented for doubly-fed induction machine (DFIM) drives. The nonlinear controller is designed based on combination of Sliding-Mode (SM) and Adaptive-Backstepping control techniques. Using the fifth order model of DFIM in a stator d, q axis reference frames with stator currents and rotor fluxes as state variables, a SM controller is designed in order...
