Abstract

The PI controller plays important role in all engineering controls. The tuning of PI controller is generally done with institutive methods, which are less effective. This paper discusses about the PI controller tuning which affects the results of the total harmonic distortion (THD) of the active power filter. The active power filter is designed for reducing the THD in non-linear load connected power system. It is identified that the variation of proportional constant (Kp) and Integral constant (Ki) affects the THD value. So a problem is formulated to minimize the THD value of the system to find the optimal Kp, Ki parameters. The well-known genetic algorithm (GA) and Particle swarm optimization (PSO) techniques are used to find the optimal value of parameters and minimum THD value. MATLAB Simulink, Sim power system and optimization tool boxes are used.
