Objective: The objective is to design PSO based I-PD Controller and PID Controller for a nonlinear system. The nonlinear system selected is Interacting Spherical Tank System. Methods: Controlling of a nonlinear system is an important process. The PID Controller and PSO based I-PD controller are designed for the non linear systems selected and the error values are calculated. The comparison of performance between these two controllers is done and result is produced. Findings: From the simulation result it is inferred that PSO based I-PD controller gives smooth response when compared to PID controller whereas error indices are less in PID controller. Applications: The spherical Tank is widely used in petrochemical industries, paper making industry, water treatment industries.
Keywords: Nonlinear System, PID Controller, PSO-Particle Swarm Optimization, Spherical Tank
