Abstract

The paper Present to design PID controller parameters for an unstable Automatic Voltage Regulator system using Particle swarm optimization (PSO). The design goal is to minimize the integral errors and reduce transient response by minimizing overshoot, settling time and rise time of step response. First an objective function is defined, and then by minimizing the objective functions using real-coded PSO, the optimal controller parameters can be assigned. The avr system taken for case study is inherently unstable, highly nonlinear and after tuning of PID using PSO, results stable system.
