Close Loop Speed Controller for Brushless DC Motor for Hybrid Electric Vehicles

摘要

Vehicle emissions are the great concern of the modern world and hybrid electric vehicles is one of the feasible solutions because it mitigates pollution and increases fuel efficiency. Power electronics plays an imperative role in Hybrid Electric Vehicle because it consists of converters for high-performance electric traction motor drives. It is important that the traction motor must fulfill the demands of the various driving cycles. In this chapter, a detailed performance analysis of controlling the speed of Brushless DC (BLDC) motor with or without disturbances (or load) is addressed. The chapter also involves the design and implementation of a controller which minimizes the initial overshoots. This work was conducted with the purpose of developing a three-phase inverter for BLDC motor drive system. The two different controllers are designed and simulated for closed-loop speed control of BLDC motor at different loading conditions. The simulation work is performed in MATLAB Simulink platform and results match with the theoretical one.
