Optimization Methodologies for Optimum Design and Comparative Performance Analysis of PID Controller

The main aim of the proposed work is to plan and execute an efficient automatic voltage regulator (AVR) system, compensated with proportional integral derivative (PID) controller for intelligent control of voltage in an autonomous electrical power generating system tuned through various soft-computing techniques i.e. ZN, PSO, MOL, PSA, GSA, GWO, CPSO, SFL, NSGA-II, and TLBO. The design objective of AVR in proposed work is to minimize transient response by PID control parameters i.e. rise time, peak time, settling time, peak amplitude, overshoot, undershoot, stability, and to compare different type of algorithms by plotting comparative graphs. The paper concludes best algorithm by giving ranking for each PID control parameter followed by the overall ranking.
