摘　　要：以智能电器课程为载体,将自动控制理论引入智能电器的教学中,采用生动、直观的方式给学生展现艰涩的控制理论转化成实际控制方案的过程。采用神经网络构建接触器的电磁吸力实时观测器,结合三位式滞环控制方法,实现接触器的直接吸力闭环控制。采用联合仿真及快速控制原型验证系统,直观呈现智能控制理论到实际控制方案的逐步转化过程,不仅便于学生理解枯燥的自动控制原理,同时有助于智能电器实践教学的逐级深入开展,实现理论与实践的融合。How to take the core course of“intelligent electrical apparatus”as the carrier,introduce automatic control theory into the teaching of intelligent electrical apparatus,and show students the process of transferring difficult control theory into practical control schemes in a vivid and intuitive way,is a meaningful work.In this paper,the neural network is used to construct the real-time electromagnetic force observer of the contactor.On this basis,the direct electromagnetic force closed-loop control of the contactor is realized for the first time by using the three-position hysteresis control method.The co-simulation and rapid control prototype verification system are used to intuitively present the gradual transformation process from intelligent control theory to practical control schemes,which is not only convenient for students to understand the boring principle of automatic control,but also conducive to the in-depth development of practical teaching of intelligent electric apparatus step by step.It realizes the integration of the theory and practice.
