“…Among the speed or position sensorless control strategies, model reference adaption system(MRAS) is widely used because of its simple structure [11][12][13][14][15]. Based on Popov super stability theory, this paper presents one novel control strategy for PMSM sensorless vector control based on MRAS.…”

The precise speed and torque controls of Permanent Magnetic Synchronous Motor (PMSM) are usually realized by using speed or position sensor. However, the mounting of speed or position sensor requires an additional space. The cost of motor drive system with speed or position sensor is high, the reliability is low and is difficult to maintain. This paper presents one novel control strategy for PMSM sensorless vector control based on model reference adaption system(MRAS). This control strategy doesn’t need any speed or position sensor and can estimate the rotor speed with a few parameters. In this paper, PMSM itself is selected as reference model, and the mathematical model of PMSM which includes estimated parameter is regarded as adjustable model. The output error of these two models is used to drive the adaption mechanism and the estimated speed is obtained. The simulation results verify the proposed control strategy is effective, it has excellent dynamic and stable responses, the estimated speed precision is high and the system is robust.

“…The linear motor sensorless control techniques can be classified into two major groups [1,2] : fundamental-excitation methods [1][2][3] and saliency and signal injection method [4,5,8] .The former estimates the rotor position and speed from the stators voltage and currents. The back-EMF or flux linkage is often used to estimate rotor position.…”

This paper presents a method of improving sensorless control based on the high frequency injection(HFI)for linear motor. The d-and q-axis incremental self-and mutual-inductance are determined by finite element analysis. The estimated mover position error caused by the cross-coupling magnetic saturation between the d-and q-axis is quantitatively analyzed. The error caused by filters in a HFI system is analyzed based upon filter group delay theory. A simple-to-design on-line compensation method is proposed based upon filters and cross-coupling magnetic saturation in a HFI system, which minimizes the position error. Finally, the simulation and experiment show a significant improvement in the accuracy of the mover position estimation.

“…It is typical of interior magnet motors that the rotor saliency complicates the application and analysis of fundamental-excitation methods [2], [5], [7]- [10], contrary to signal injection methods. The stability of the drive system is the most crucial design criterion [6], [8]. In this paper, an observer gain providing a stable and well damped system is proposed based on the linearized model of the system.…”

Abstract-This paper deals with a speed and position estimation method for the sensorless control of permanent magnet synchronous motors. The method is based on a speed-adaptive observer. The dynamics of the system are analyzed by linearizing both the motor model and the observer, and the observer gain is selected to give improved damping and noise suppression. At low speeds, the observer is augmented with a signal injection technique, providing stable operation down to zero speed. The experimental results, obtained using a 2.2-kW interior magnet motor, are in agreement with the results of the analysis.
