| 摘 要： | 提出一种基于微分几何的精确反馈线性化控制方法,介绍其基本概念及在交流电机调速系统中的应用原理.分析了磁场定向控制的局限性,即它只能获得渐近的输入-输出线性化和解耦.而采用基于微分几何的精确反馈线性化方法,即使在磁场变化的情况下系统暂态响应也是解耦的,这有利于改善交流电机这类具有非线性特征的电气传动系统的性能.

| Abstract: | It is forwarded the new control method with accurate feedback lineadzation based on differential geometry. Also introdaced are its basic concepts and the application principle of speed adjustment of AC motor, Limited application of field-oriented control is analyzed, through which only input/output linearization and decoupling could be obtained. And by accurate feedback linearization based on differential geometry the temporary response is decoupling even if the field is changing, which facilitates the improvement of AC-drive system performance of AC motors featuring nonlinearity. |
