Abstract

This paper proposes the Sensorless Speed Control of Permanent Magnet Linear Synchronous Motor (PMLSM) using Extended Kalman Filter (EKF). Linear Speed and position of PMLSM is estimated using EKF. The mathematical model for PMLSM & EKF is established. The simulation model for sensor and sensor-less speed control of PMLSM using EKF is constructed using MATLAB/ SIMULINK. The linear motor speed and position are compared for both sensor and sensorless using EKF. It is observed that the estimated speed and position values are almost similar to actual values. Though it has disadvantages such as complex algorithm and larger matrix operations, sensorless speed control eliminates the requirement of mechanical sensor and hence reduces the drive cost and enhances reliability.

Keywords
