摘要
介绍了考虑端部效应后直线感应电机在两相同步旋转坐标系下的数学模型,并对速度与反应板对端部效应的影响进行了分析。在此基础上讨论了直线感应电机转差频率控制方案的可行性,并给出了控制方案。采用Matlab/Simulink构建了直线感应电机数学模型并对其转差频率控制进行了仿真。仿真结果验证了控制方案的可行性。
The mathematical model of the linear induction motor is introduced, taking into consideration the terminal effects in two-phase synchronous reference frame. Also analyzed is the influence of speed and reaction board on the terminal effect. The program feasibility is further discussed for the slip frequency control of linear induction motor and the control program is proposed. The mathematical model of the linear induction motor is built with Matlab/Simulink and its slip frequency control is simulated. The simulation results verify the feasibility of the control program.
