Delay compensation using PID controller and GA

This paper discusses the using of PID controller to compensate delay component that frequently appears in a control system. The delay component is known to not only make time-lag in system response, but also reduce system stability, thus, it needs to be compensated to improve the stability. To determine optimal parameters in the PID controller, the genetic algorithm is used and the results are compared to the results of two standard PID tuning methods: the Iterative Method and Ziegler-Nichols rule.
