Study on fuzzy-neuro immune self-adaptive PID controller for pipe racking system

A novel control scheme, fuzzy-neuro immune self-adaptive PID controller, was put forward aiming at the location accuracy problem for Pipe Racking System. The proposed scheme was designed based on the traditional PID theory, biology immune response mechanism and fuzzy control method. In addition, by adopting robust feedback controller, the stability that the closed-loop system in initial stage of fuzzy neural network learning was also guaranteed. The experimental results show that the fuzzy-neuro immune self-adaptive PID controller has a high control performance. The control method has fast response, no overshoot, strong robustness, self-adaptation, high control precision and it can meet the requirements of the nonlinear system, there is certainly feasible.
