摘要
基于输入输出反馈线性化理论,选取一种新的异步电机仿射非线性模型后,提出了一种不引入零动态的异步电机反馈线性化控制策略,避免了对系统零动态稳定性问题进行复杂的分析。求解了解耦矩阵使得系统可等价为两个相互解耦了的独立的线性系统,简化了异步电机调速系统的控制器设计。仿真结果及实验结果表明:所提出的不引入零动态的异步电机反馈线性化控制方法有效实现了异步电机这个非线性被控对象的解耦控制,系统的动静态性能优良,鲁棒性好。
A feedback linearization control strategy of induction machines which features not introducing zero dynamics is proposed based on the input-output feedback linearization theory after selecting the novel affine nonlinearity model of induction machines. As a result, the complicated analysis of the stability of the zero dynamics is avoided. In order to make the system be equivalent to the two decoupled independent linear systems, the decoupling matrix is derived, therefore, the design of the controllers for induction motor speed control systems is simplified. The simulation results and the experimental results show that the decoupling control of induction machines, which are nonlinear controlled objects, is effectively realized via the proposed feedback linearization control strategy of induction machines without introducing zero dynamics, the static and dynamic performance, and the robustness of the system are excellent.
