This paper designs a novel control method for energy efficient and wide speed range drive of the PMSM. The proposed method includes several parts: (1) using a PI speed controller to create a signed current norm value as input of the command converter. (2)The command converter can simply and accurately generate an analytical current command according to the current control standard satisfying the maximizing/current...
A novel PID controller based on particle swarm optimization (PSO) has been applied to permanent magnet synchronous motor (PMSM). The PSO controller has replaced the conventional PID controller in the speed-regulation loop of vector control. It is intelligent and convenient to find the PID parameter. Experimental results have also demonstrated that PMSM which uses the PSO controller has better robustness...
Permanent magnet synchronous motors are used in many industrial applications because they have several inherent advantages. However, information about the rotor position is necessary even to be able to control drive speed. Conventional speed and position detection uses encoder and resolver. These sensors significantly increase price, weight, and degrade reliability. Therefore many authors publish...
Permanent magnet synchronous motors are used extensively in high performance control systems according to developments in power electronics and control technology. In this work, performance comparison of Permanent Magnet Synchronous Motor (PMSM) is made by performing speed control.

The paper studies sliding mode variable structure control system for a novel gearless windlass balance oil pumping unit (GWBOPU) driven by low-speed and high-torque permanent magnet synchronous motor (PMSM). By analyzing the correlative relationships of the motor and the load, a mathematics model for GWBOPU is established. Base on this model, a speed sliding mode controller is designed by regarding...
A new velocity and torque control strategy based on the direct control of stator flux linkage is introduced due to the disadvantage of permanent magnet synchronous motor circuit vector control and traditional direct torque control. By controlling the trajectory of stator flux linkage vector, flux linkage and torque control are achieved, thus permanent switching frequency and small flux linkage pulse...
This paper introduces a new simple sensorless algorithm of estimating the permanent magnet synchronous motor (PMSM) speed and position. The proposed estimation method is implemented using a stator flux/current and a modified back electromotive force (EMF) observer connected in cascade. The flux/current observer based on sliding mode techniques ensures stator currents convergence while the modified...

This paper propose an adaptive sliding mode observer(SMO) which adds an estimation function for the stator resistance to the conventional sliding mode observer. It is proposed for the robust sensorless control of permanent magnet synchronous motor(PMSM) with variable parameters. The low-pass filter and additional position compensation of the rotor are used to reduce the chattering problem commonly...
A novel energy-shaping controller design technique is used to the speed regulation of permanent magnet synchronous motor (PMSM). Using interconnection and damping assignment passivity-based control (IDA-PBC) methodology, assigning a desired port-controlled Hamiltonian (PCH) structure to the closed-loop PMSM system, speed controllers are designed when the load torque is known and unknown, respectively...
Forced dynamics control principles are exploited to develop control algorithms for electric drive with PMSM and flexible couplings. The controller is of the cascade structure, comprising an inner speed control loop, which respects the principles of vector control and requires a load torque estimate and an outer position control loop, which is designed to control the PMSM rotor or load angle in the...
Sensorless speed and position control of permanent magnet synchronous machine still is a challenge especially for surface mounted permanent magnet synchronous machines. This paper describes the high frequency signal injection based technique for control of surface mounted permanent magnet synchronous motor. Due to the fact that it does not use the fundamental machine model, which fails at standstill...
