Mathematical Modeling of BLDC Motor Using Two Controllers for Electric Power Assisted Steering Application

摘要

The improvement in the field of engineering and technology over last decades made BLDC Motor application possible in the automotive industry. This paper deals with one such application. This paper gives a steering control system using two controllers namely a hysteresis controller and a PID controller. This system reduces the noise and it is more accurate than the mechanical system which is used presently in the vehicles. The controller uses two reference techniques to estimate torque and speed of BLDC motor. The controller was simulated for various load side disturbances and found to exhibit better controlling capability than existing methods.
