Abstract
The optimal design of the proportional-integral-derivative (PID) controller for an antenna azimuth position control system by using the Levy-flight intensified current search (LFICuS) algorithm is proposed in this paper. The LFICuS is one of the newest and most effective metaheuristic optimization search techniques. Based on the modern optimization context, the error between the desired azimuth angle input and the azimuth angle output is set as the objective function to be minimized by the LFICuS via searching for the optimal parameters of the PID controller. The optimal PID controller designed by the LFICuS is compared with that designed by the Ziegler-Nichols (ZN) tuning rules. As results, an antenna azimuth position control system with the PID controller designed by the LFICuS can provide very satisfactory responses without steady-state error and with less settling time, smaller oscillation and overshoot than that designed by the ZN.
