【摘要】 提出了一种采用二阶自抗扰控制器(ADRC)的感应电动机空间矢量脉宽调制和直接转矩控制(DTC-SVM)策略,并对控制器的核心部分——扩张状态观测器(ESO)的稳定性进行了分析和推导,同时将推导出的稳定条件作为自适应遗传算法的约束条件对自抗扰控制器的参数进行优化。仿真结果表明,新策略有效改善了转速和转矩的动态响应,而且二阶ESO稳定条件对基于遗传优化的ADRC参数整定具有一定的参考价值。更多还原

【Abstract】 Proposed a new DTC-SVM strategy with the second-order ADRC in this paper,and investigated the stability conditions of the key segment of ADRC-ESO,which were employed to design the parameters of ADRC based on adaptive GA optimization.Simulation results showed a significant improvement in dynamic performances of the speed and torque responses,and the stability conditions of ESO provide reference value for the parameter modification of ADRC based on GA optimization.更多还原
