Abstract:

In order to solve the micro-arc oxidation system problem, such as:digitization is low and the operation is not convenient enough,a control system scheme of artificial intelligence in micro-arc oxidation power supply based on DSP is proposed. Micro-arc oxidation system, the hardware of the power supply and software of the power supply is designed at the same time. Power output is stable and real-time have been improved by the use of software PID and hardware PID adjustment. In addition, the belief network model is used to predict the film thickness after micro-arc oxidation,at the same time through the storage of operational data effectively improve the system's human-computer interaction. Practical application shows that the system is easy to operate, excellent process adaptability, scalability excellent and real-time outstanding meet the design requirements.
