This paper proposes the predictive controller design for a sensorless interior permanent magnet synchronous motor drive system. The predictive controllers include a current-loop predictive controller and a speed-loop predictive controller. By using the proposed control algorithms, the closed-loop sensorless interior permanent magnet synchronous motor drive system can achieve fast transient responses,...
This paper proposes an adaptive inverse controller design for a micro-permanent magnet synchronous motor control system. The adaptive inverse controller is constructed by using an adaptive model and an adaptive controller. The parameters of the adaptive model and adaptive controller are on-line tuned. By using a state estimator, the speed signal is obviously improved. In addition, the control system...
This paper proposes the design and implementation of adaptive controllers for a sensorless synchronous reluctance drive system with direct torque control. Two adaptive control algorithms, which include adaptive back-stepping control and model-reference adaptive control, are proposed to improve the performance of a sensorless direct-torque controlled synchronous reluctance motor drive system. A digital...
This paper proposes a novel advanced controller design for a sensorless interior permanent magnet synchronous motor position control system. An adaptive controller is proposed to obtain a good transient response and a good load disturbance rejection capability. The proposed control method can be applied in a position control system without using any position sensor. By using the Lyapunov stability...
