Design of an Artificial Intelligence PID Controller

PID control is widely used for its simple algorithm and convenient parameter adjustment. But general PID controller is not efficient and robust because of the not fully optimized parameters. The article designs an artificial intelligence PID controller, which adjusts and optimizes PID parameters according to the real time application scenario. The controller uses normal function to simulate fuzzy control rule and to optimize the parameters of PID controller. Application in missile autopilot design shows that the controller is robust and has short response time, high accuracy.
