In this paper, a robust and an efficient tracking controller based on model reference adaptive system (MRAS) technique is performed for mobile robot in order to get the accurate trajectory tracking performance. The model reference adaptive system (MRAS) technique has been presented so as to achieve the estimated value of system's speed information. To estimate the rotor position and speed of the mobile...
This paper studies the senserless control of surface-mount permanent magnet synchronous motor (SPMSM) based on model reference adaptive system (MRAS) method. We focus attention on how parameter variation and dead-time influence the speed and position estimation error of the sensorless control strategy. Comparison of different impacts caused by each parameter variation is realized using Matlab/Simulink...
In the paper selected results of study of the low speed range Permanent Magnet Synchronous Motor (PMSM) sensorless drive are presented. This drive uses the position estimator, which is based on the back electromotive force (BEMF) observer. The drive was tested by simulation and in laboratory. It works properly especially in projected range of the speed, which covers the speed in a single revolutions...
Sensorless speed control of Permanent Magnet Synchronous Motor (PMSM) is still in development to eliminate the existing drawbacks such as speed ripples, torque ripples and slow response. This paper proposes Field Oriented Control (FOC) based on improved Model Reference Adaptive System (MRAS) to control the motor speed and minimize both the speed and torque ripples for the PMSM. The improved MRAS strategy...
This paper is intended to compare and study the operation of two methods for estimating the position and speed of the rotor salient pole synchronous system in a sliding mode control motor. The first method (MRAS) is based on the dynamic model of the salient pole PMSM, formulated in a reference frame linked to the rotor. The second method, based on a nonlinear Luenberger extended observer is used to...
This section presents a structure of a control topology of a PMSM, whose objective is to eliminate the mechanical sensor and ensure continuity of service even fault presence opening a phase. A MRAS observer is used to replace the mechanical sensor and a redundant inverter leg is used to replace the faulty leg.
Permanent magnet synchronous motors (PMSM) are appropriate for applications with load-independent speeds or synchronous operation with high accuracy under defined speed. In this paper analysis the structure and equations of the PMSM, direct torque control (DTC) and voltage space vector process then study model reference adaptive system (MRAS) estimators. The PI controller uses from estimate speed...
Speed identification is important to apply the permanent magnet synchronous motor system on the situation that need speed signal but without speed sensor. Taking system dynamic mathematics model as the investigated subject, set up the speed identification adaptive system of the enhanced magnetism motor system on the basic of model reference adaptive system and POPOV's hyperstability theory. Derive...
The sensorless control of PMSM are mostly based on high frequency voltage signal injection method or state-observer. A novel rotor position self-sensing method was put forward in this paper by combing the fluctuating high frequency voltage signal injection (FHFVS) method and model reference adaptive system (MRAS) method, which was used in maximum ratio of torque to current control system. The speed-switcher...
