Abstract

This article proposes a significant application of the current search (CS), one of the novel meta-heuristic optimization techniques, to control synthesis problems. The CS inspired by an electric current flowing through electric networks is conducted to synthesize an optimum PID (proportional-integral-derivative) controller for stabilizing two unstable plants, i.e. inverted pendulum and ball-beam systems. As simulation results, optimum PID controller giving very satisfactory responses can be achieved by the CS.
