Novel Technique of Optimizing FOPID Controller Parameters Using BBBC for Higher Order System

ABSTRACT

The authors present a computer-aided mode to optimize the fractional-order proportional integral derivative (FOPID) controller parameters including the integral order “λ” and derivative order “μ”. Big Bang–Big Crunch (BBBC) optimization technique is used here to serve the purpose. The proposed method is realized with a numerical example and unit step responses are obtained for various values of λ and μ. The simulated results justify the superiority of FOPID controller using BBBC, when compared with the recently published/available well-known method.

Keywords:

• Fractional-order proportional integral derivative
• Big Bang–Big Crunch
• Optimization technique
