In this paper, the speed regulation problem for permanent magnet synchronous motor (PMSM) system under vector control framework is studied. First, a speed regulation scheme based on standard internal model control (IMC) method is designed. For the speed loop, a standard internal model controller is first designed based on a first-order model of PMSM by analyzing the relationship between reference...
Many high performance industrial and traction permanent magnet synchronous motor (PMSM) drives require position sensorless operation. Most of the sensorless control techniques are dependent on motor parameters, such as stator resistance, inductance, and torque constant. Thus, the performance suffers greatly in harsh and highly dynamic operating conditions, where the motor parameters are changing....
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...
Vector control has been widely used in control of permanent magnet synchronous motors (PMSM) where the rotor position information is required. The cost of mechanical sensors and the difficulty to incorporate them make it necessary to avoid their uses and to study the mechanical Sensorless control. The idea behind such methods is to extract the motor position and speed information in functions of the...
