PID Controllers for BLDC Motor: A Comparative Study

Abstract

Due to various environmental problems such as global warming, air pollution, and fossil fuels depletion, Electric Vehicles (EVs) are in more demand. Recently a lot of research is being done on the development of electric vehicles. The controller of an EV is considered as one of the most important parts as it controls the speed of the motor. Brushless DC motor (BLDC) has a great demand in EVs as it has a simple design, high applied output force (torque), long-term usage, and speed stability. While BLDC frameworks are portrayed by their vulnerabilities and non-linearity. As a result, controlling this motor is a significant concern. Similar to how a carburetor controls acceleration and speed in a gasoline-powered vehicle, the electronics package that controls the electric vehicle operates between the motor and the batteries. Engine regulators go about as the significant part which controls the energy stream to the engine. The motor controller processes commands from these inputs and precisely controls the speed, torque, direction, and horsepower of a vehicle motor by connecting interfaces like throttle, brakes, or forward/reverse control switches. BLDC engines can be subbed to make the enterprises more powerful. The Proportional Integral Derivative (PID) algorithm, which can more effectively improve the speed control of BLDC motors, is used in this paper to describe the design of the BLDC motor control system. The reason for the paper is to give an outline of the usefulness and plan of the PID regulator, for example recurrence reaction tuner and move capability tuner. At last, the review goes through a few well-working tests under various burden force conditions that will uphold that the PID controller is undeniably more relevant, better functional, and powerful in accomplishing good control execution contrasted with different regulators.
