摘要
根据异步电动机转子电阻和负载转矩随运行工况而变化的事实,拟应用微分几何多输入、多输出线性化解耦控制理论和模型参考自适应理论,研究提高电动机鲁棒性能的控制策略。最终得到磁链和转速动态解耦的2个二阶子系统。仿真结果表明,该控制策略能够有效解决系统内部参数的摄动和外部参数的扰动影响,系统控制鲁棒性高。
Induction Motor is a muhivariable,nonlinear controlled object,its rotor resistance and load torque vary when rotor runs~ According to actual facts,the nonlinear decoupling control tragedy based on theory of differential geometry and model reference self-adaptive theory when motorg parameter varies is designed, finally two separate two-order flux and speed subsystems are presented. Simulation experiment verify the proposed control scheme better solves system robustness problem,
