Comparison of PI and ADRC Current Controllers for IFOC-Driven Synchronous Reluctance Motors

Abstract

Currently, electric motors are used in various industrial applications and electric vehicles, leading to increased research and development in efficient propulsion systems and cost-effective design. Reluctance synchronous motors (SynRM) are among alternating current electric machines, owing to their simple and robust design. The objective of the article is to design a high-performance control system. Initially, the indirect field-oriented control using PI controllers will be implemented for driving the SynRM. Subsequently, these controllers will be replaced by controllers with active disturbance rejection (ADRC). Simulation for this control system is conducted using Matlab/Simulink software. Finally, the results show better performance from the ADRC current controller than the PI controllers. The ADRC provides faster response times, better tracking capabilities, real-time disturbance rejection, and reduced ripples.
