中文摘要： 低压电磁电器智能化控制技术的发展，由于机构动作分散性、吸合过程铁心与触头的弹跳、分断过程触头之间电弧等诸多因素的影响，受到制约。对交流电磁电器而言，系统相位角、幅值等参数随时间变化，使得交流开关器件在不同的时刻合闸或分闸时，电压和电流的差别很大，影响其动作特性的因素更加不确定，因而智能化控制难度更大。能否借助现代控制理论、仿真技术、实验研究等手段，彻底改变传统低压电器的工作模式，形成具有自学习和自主控制的新一代开关电器，是本课题想要解决的问题。课题以交流接触器为研究对象，通过实验研究与仿真设计相结合的方法，寻找不同相角情况下，交流接触器特性的影响因素，得出最佳吸合过程和分断过程的控制模式，采用形态小波算法，寻找能够反映接触器触头参数的特征参量，结合现代控制技术研究交流接触器全闭环实时在线控制的相关技术和相关理论，希望形成电磁电器新控制思路。项目属于交流电磁电器智能控制领域的应用基础研究。

英文摘要： The development of intelligent control technology for low voltage electromagnetic devices is restricted by the dispersibility of mechanism action, the bounce of iron cores and contacts in the closing process, the arc produced between the contacts in the opening process and so on. For the AC electromagnetic devices, the parameters such as the phase angle of system, the amplitude and so on are varied by the time. It will result that the value of voltage and current in different moments of closed or open are quite different. It will add the uncertain of the reasons which affect the operating characteristic. Therefore, it will be harder to realize the intelligent control. The project makes use of the modern control theory, simulation technique, experimental study and so on to change the operating mode of the traditional low voltage appliance and forms a new kind of switching apparatus with the self-study and autonomous control. The project makes AC contactor as the research object. It takes advantage of the combination of experimental study and simulation design to search for the influence reasons of AC contactor characteristic and the control mode of the best closing and opening process can be got. The morphological wavelet algorithm is used to looking for the characteristic parameters which reflect the parameters
