Abstract :
The parameter of dissolved oxygen is one of great importance in the process of microbe fermentation. A normal PID is difficult to solve the nonlinear, time-delay characteristics. A intelligent PID controller is designed based on dynamic inertia factor PSO, which can adaptively adjust the parameters of PID and is used in the control of DO. Compared with normal PID controller, the new controller is of small overshoot and quick response, improved stability of the system and increase the yield of products.
