The purpose of this paper is to design a PID controller by using PSO, GSA, and PSOGSA control techniques for MLS. A conventional PID control technique (tuned by Ziegler Nichols Method, ZN) is used to control the stability of the MLS. However, PID-ZN has the limitation usually produces a high value of overshoot. Therefore, to achieve optimal performance, PSO, GSA, and PSOGSA are adopted for tuning the PID controller. Also, the arrangement between PID-PSO, PID-GSA, and PID-PSOGSA are compared to find the best control technique for the MLS. The result of this paper shows PID-PSOGSA has the best performance compared to PID-PSO, PID-GSA, and PID-ZN in terms of percentage overshoot, settling time, rise time, and sum square of error.
