Applying of PID, FPID, TID and ITID controllers on AVR system using particle swarm optimization (PSO)

Some methods are available to optimize problems such as Particle Swarm Optimization (PSO)-which is a computational method-by having a population of candidate solutions. In this paper we presented four PID, FPID, TID and ITID controllers and applied each one on four different error functions in an AVR system by means of PSO algorithm. This performance led us to a specific conclusion and also a comprehensive result was drawn out of the system´s response and diagrams. According to rising time, settling time and overshoot percentage, we gathered a presentation that helps everyone to find the best controller easily while working with different error functions.
