| 摘 要： | 针对交流电动舵机系统非线性,多变量和强耦合的特性,提出了一种基于微分几何方法和变结构控制理论的非线性解耦控制方法。建立了交流电动舵机的非线性模型,利用微分几何理论,通过对系统进行微分同胚变换和反馈变换,实现了非线性系统的精确线性化和输入/输出解耦,并针对电动舵机系统参数摄动和负载扰动的特点,利用指数趋近律设计了电动舵机的变结构控制器。仿真结果表明不仅可以有效地实现交流电动舵机系统的非线性解耦,具有良好的静、动态特性。

| Abstract: | A nonlinear decoupling control method based on differential geometry and variable structure control theory was proposed in this paper according to the nonlinear,multi-variable and strong coupling characteristics of AC electromechanical actuator system.An affine nonlinear model of AC electromechanical actuator was firstly established,the exact linearization and input/output decoupling of system were then realized through differential homeomorphism and feedback transformations.On the basis of this,a variable ... |
