Comparison of Fuzzy Control and PID Control

As it knows most of the quotidian types of control, problems are not simply to evaluate and considerate formal modelling based in traditional techniques. The process control makes the evaluation and executions more efficient in the industry. This article was made with the purpose to compare two types of control, one with FUZZY logic and second one PID control. Here we have developed temperature control system using fuzzy logic. The flyback converter with voltage doubler rectifier acts as an output module. To overcome the efficiency degradation during lightload due to load dependent soft switching of the ZVS, a control method using pulse width modulation (PWM)proportional to the load current is us Comparison between Fuzzy logic controller & PID controller based on pulse width modulation is proposed and the results are analysed. Thus, comparing the result PID controller gives more accurate results than first Fuzzy logic controller.
