Improvement event based PID controller using fractional order technique and genetic algorithm

In this article a fractional order controller is presented to improve the response of the event based PID controller. First a conventional PID controller is tuned using MATLAB tuner software. Then a fractional order PID is tuned using genetic algorithm. According to simulations , by combining the event based technique and fractional order controller, a noticeable improvement in system response can be seen. Besides, reduction in control input updating is very helpful in reduction the communication bandwidth waste.
