【摘要】 在分析异步电机数学模型基础上,提出了异步电机控制系统仿真建模的新方法。在Matlab中,建立独立的功能模块,如电机本体模块、矢量控制模块、速度控制模块、电流滞环控制模块等,再进行功能模块的有机整合,构建交流异步电机控制系统的仿真模型。系统采用双闭环控制:速度环采用PI控制,电流环采用电流滞环控制。仿真结果证明了该方法的合理性、有效性,为实际电机控制系统的设计和调试提供了新的思路。更多还原

【Abstract】 Based on the mathematical model of asynchrony motor, a novel method for modeling and simulation of asynchrony motor control system in Matlab has been proposed. In Matlab, the independent functional block such as Moter model block, Vector control block, Speed controller block and Hysteresis current controller block etc, have been modeled. The model of control system can be established easily by the organic combination of these blocks. The double loop is adopted in controlling system, a PI controller is adopted in the speed loop and a hyteresis current controller is adopted in the current loop. The reasonability and validity of it have been testified by the simulation results and this novel method offers a new thought for designing and debugging the actual controlling system of motors.更多还原
