Design of an H∞ PID Controller Using Particle Swarm Optimization
Majid Zamani,Nasser Sadati,Masoud Karimi Ghartemani 제어·로봇·시스템학회 2009 International Journal of Control, Automation, and Vol.7 No.2
This paper proposes a novel method to designing an H∞ PID controller with robust stability and disturbance attenuation. This method uses particle swarm optimization algorithm to minimize a cost function subject to H∞ -norm to design robust performance PID controller. We propose two cost functions to design of a multiple-input, multiple-output (MIMO) and single-input, single-output (SISO) robust performance PID controller. We apply this method to a SISO flexible-link manipulator and a MIMO super maneuverable F18/HARV fighter aircraft system as two challenging examples to il-lustrate the design procedure and to verify performance of the proposed PID controller design method-ology. It is shown with the MIMO super maneuverable F18/HARV fighter system that PSO performs well for parametric optimization functions and performance of the PSO-based method without prior domain knowledge is superior to those of existing GA-based and OSA-based methods for designing H∞ PID controllers.
