Modelling and Control of Brushless DC Motor

EasyChair Preprint 5710

Abstract

Brushless direct current (BLDC) motors, also known as permanent magnet motors perceives vast applications in many industries due to their high efficiency, reliability, durability and ease of control. The paper introduces a model of three phase brushless dc motor and its different control mechanism. The major target of the paper is to present three different control techniques to stabilize each state of the plant with the aim to achieve high performance of BLDC motor in MATLAB/SIMULINK. The paper also describes motive to check the ability of each control technique to force the rotor to follow a preselected speed/position track. The first control approach designed sis conventional PID controller which reduces the steady state error of the system and gives a stable response at each state. The other two advance control techniques used are SMC which has given more efficient response by tracking the reference effectually in presence of disturbance and MPC also has given best performance at each state by effectively predicting the values in the presence of constraints. By the comparison of results it has been found that the proposed control approaches stabilizes each state of the system and have achieved better results with disturbance.
