Speed control simulation of DC servomotor using hybrid PID-fuzzy with ITAE polynomials initialization

Abstract

DC motor is widely used in industrial process, which includes automation and robotics process. DC motor has many advantages than AC motor, such as: it has wide range controllable speed without influences its quality input of power, it has high output torque, simpler construction than AC motor, it does not result lossless of reactive power, and it does not yield harmonic to the supplying system. In order to produce optimal operation, the speed of DC motor must be controlled. The speed can be controlled using some methods, such as: conventional PID, Ziegler Nichols based PID controller, Transient Response Specification based PID controller, and Hybrid PID-Fuzzy. The aim of this research is to analyze the speed control of DC Motor using Hybrid PID-Fuzzy method and compares its output performance with conventional PID method. The output performance among these method will be compared using calculation of their ITAE polynomials output. Modeling and simulation have been done in MATLAB-Simulink and it shows the better performance compared with classical PID method.
