Abstract


In the producing technique of electronic products, wave soldering is a main method of soldering. The control performance of the control system affects the soldering quality of electronic products. The paper introduces the design of the control system of wave soldering machine and its controller. The paper has a deep research on the algorithms of PID autotuning and delay compensation.The main job of the paper has been done includes:1. The design of the control system of wave soldering machine and its controller.2. Summarizing all kinds of algorithm of PID autotuning. And an algorithm of PID autotuning based on relay feedback is discussed on detail.3. The paper also discusses the application of delay compensation algorithm based on relay feedback identification model to temperature control. A fuzzy control based on Smith predictor is used and have received a good performance.4. Local debugging of the wave soldering control system.The experiment result proves that the wave soldering control system has a good structure and high reliability, good performance.
