Linear Hall Sensors-Based Sliding Mode Control for Permanent Magnet Linear Synchronous Motor Drive Systems

Abstract

In this paper, a sliding mode control (SMC) method for permanent magnet linear synchronous motor (PMLSM) based on linear Hall sensors is proposed. Firstly, a new linear motor configuration and linear Hall sensor equipment are employed, such suitable for more complex operation environments. Next, an arctangent function-based method to calculate the electrical angle is proposed, and STM32F407 is used as the main control chip to demonstrate it. Then, a sliding mode controller (SMC) is designed to improve the tracking performance and anti-disturbance performance of the system. Finally, the effectiveness and superiority of the proposed control strategy is illustrated by the research results comparing with the conventional proportional-integral-derivative (PID) control strategy.
