Research Of Methods Of Neutral Network Controlling Based On PAC

The level of industrial automation has been an important symbol of weighing modern level of other area at the moment.PID controller, as a classical controlled methods, duing to its simple structure, not depending on the mathematical model of controlled object and the advantages of strong robustness, has been an important method of process controlling area. In this paper, BP neutral network PID control and traditional PID control were compared combined with three classical neutral network controlled methods. And a PID controlled platform was designed based on the basic structure of PAC and its operating principle.In this paper, classical PID principle of control was studied firstly, especially the principle of digital PID controller. Lately, classical PID parameter tuning methods was studied. It also studied the basic structure and principle. At last, several classical controlled algorithm were proposed, including BP neutral network control, RBF neutral network control and CMAC.Moreover, this paper put more emphasis on the research based on PID control principle and its algorithm realization. For the specific model in the industrial process control, this paper made PID controlling simulation figures and traditional PID control simulation figures. And the result of comparing both proved that neutral network PID control has better control performance.In the end, this paper studied the basic structure and work flow of PAC.A module was designed based on neutral network PID control combined with neutral network controlled algorithm. It also made the work flow of neutral network PID control based on PAC.
