| 摘 要： | 研制了一种用于电阻点焊电源的新型控制策略——预测-优选控制.在采用同一规范参数进行批量点焊加工过程中,该控制策略测量已进行的各次点焊过程的各通电周期的控制效益并进行优选;对于当前进行的点焊过程的某一即将开始的通电周期,则根据前几个通电周期的实测控制效益预测可能的控制效益,并结合之前已优选的同一通电周期的控制效益,进行综合比较与决策,得到所需的控制效益,从而给出控制输出.

| Abstract: | The author developed a new control tactics-predicting and optimizing control adapted to in the resistance spot welding power supplier.The control efficiency of each controlled electrifying period of all welding processes conducted under the same parameters has been measured and optimized.Before one period beginning at once,a probable control efficiency is predicted from the practical control efficiency of several former electrifying period in the same welding process.In combination with the control efficiency optimized in the passed welding processes, the optimum control efficiency is determined, and the control instruction is determineed. |
