PID controller for nonlinear system using cuckoo optimization

In this paper, nature inspired cuckoo based proportional-integral-derivative controller is designed for nonlinear system. The cuckoo optimization is used to tune the parameters of PID controller. Performance criteria such as ISE, ITSE and IAE are optimized by using this optimization technique. For this optimum value of performance criteria, controller parameter is selected. These parameters of controller are used to stabilize the plant or give the desired response. To generalize the proposed technique inverted pendulum, ship roll dynamics and Van der Pol oscillator (VDPO) are taken as examples of nonlinear systems. The simulation results showed the desire performance of the systems. Result has been compared with some other standard technique proposed in the past research.
