Robust PID Control System Design Using ITAE Performance Index (DC Motor Model)

Atayeb Omer Shuaib, Muawia Mohamed Ahmed

One of the most important issues in control system design is to ensure the stability of the plant. PID controller used in industrial solutions still represents the most common controller in industry. However PID can only guess stability area and indicates stability zone by trial and error together with the experience of the designer. Decrement of system performance index leads to easier and better control system stability. Integral time absolute error (ITAE) is one of the most criterion used to reduce system error and give the best PID gain values for a desired system response requirements. This paper discusses the steps used to obtain a proper PID gain parameters values using ITAE method.
