| 摘 要： | 针对三相异步电动机这个非线性、强耦合控制对象,利用自抗扰控制对不确定对象的适应性和对系统未建模动态及参数摄动的鲁棒性,提出基于自抗扰控制的空间矢量直接转矩控制策略,借鉴自抗扰控制思想,引入不连续投影算子加以修正,解决了标准扩张状态观测器对时变外扰无法保证观测误差有界的问题,设计了速度环和磁链环控制器,并通过Lyapun...

| Abstract: | Considering the nonlinearity and strong coupling characteristics of induction machine,a direct torque controlled space vector modulation strategy was proposed based on ADRC which was compliant with uncertain objects and was robust to imperfect modeling and parameter variation.The classical extended state observer(ESO) not guaranteeing boundedness of observing error with time-varying disturbance was solved by discontinuous projection operator modification.The speed/flux controllers were developed by using th... |
