A novel speed sensorless direct torque control system-SVM-DTC of permanent magnet synchronous motor (PMSM) based on SVM and MRAS is presented. In this paper the various components of the speed sensorless SVM-DTC and the principle of realization are discussed in detail. Finally the simulation results with the application of MATLAB/Simulink show that the speed identification algorithm is accurate and...
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...
In this paper, a nonlinear control approach for permanent magnet synchronous motor (PMSM) drives, without mechanical sensors, is presented. The proposed method is based on a combination of the well-known nonlinear regulation technique, state-dependent Riccati equation (SDRE), and its filtering counterpart (SDREF) which is derived by constructing the dual of this control method. The SDREF is designed...
System with mechanical speed sensor has lower reliability and higher cost. Traditional direct torque control method has disadvantages of big ripples on current and flux linkage and torque. To solve these problems, the Extended Kalman Filter is established to estimate both stator flux linkage and rotor speed. Therefore, speed sensorless direct torque control for surface permanent magnet synchronous...
The paper presents a fuzzy logic controller (FLC) for permanent magnet synchronous motor (PMSM). The fuzzy logic controller is used for speed control of this type of motors. The dynamic response of (PMSM) with the proposed controller is studied during the starting process and under different load disturbances. The effectiveness of the proposed fuzzy logic controller is compared with that of the conventional...
Electric Vehicle (EV) is a dream for the human being city traffic without exhausting gas and with low noise. Permanent magnet synchronous motor (PMSW) became at the top of AC motors in high performance drive systems such as EV. This paper describes a full digital system to control a PMSM used in EV driving by TMS320F2812 DSP. Based on the analysis of the mathematical model of PMSM, the constant torque...
In the present work an artificial neural network (ANN) based speed controller and speed estimator of PMSM (permanent magnet synchronous motor) drive is designed and simulated using SIMULINK under MATLAB and results are compared with conventional PI controller and observer based drive of PMSM. The performance of ANN based system is evaluated for various disturbances to substantiate the proposed control...
