Modeling and Analysis on PID Feedback Control of Advanced manufac-turing Mode Competition Diffusion

To control the advanced manufacturing mode diffusion and obtain the desired diffusion effect, this paper firstly studies the modeling and analysis of advanced-manufacturing-mode competition diffusion (ACD) by PID feedback control method. First, the influencing factors of ACD process and its external intervention are analyzed and practical strategies and their corresponding control units are discussed. Combining with external intervention, the basic thinking and strategies of controller design are given. Then, as to the referred input, PID feedback controllers are designed, and PID feedback control model of ACD are built. And then, the properties of control model are analyzed, and qualitative results are given. Finally, the application of the proposed model is simulated by Matlab 7.1 in a case study of practical advanced manufacturing modes diffusion. The results are consistent with the qualitative analysis, thereby verifying the correctness of the proposed model. This work discloses external intervention rules in ACD, designs the PID feedback controller, decreases the blindness of pole assignment control method, and realizes the control on ACD to desired diffusion effect both in theory and in practical strategies. It also provides theoretical basis, control methods and intervention strategies for enterprises’ decision making and government regulation.
