摘要
对于非线性电力传动对象和非线性PD反馈控制器组成的整个模糊控制系统,进行了稳定性分析,并且给出了非线性PD反馈控制器的增益参数设计,其中,非线性电力传动对象是用模糊Takagi and Sugeno模型描述的。提出了模糊系统中的状态微分反馈控制,并且有效地分析了整个控制系统的稳定性。设计方法最终被归结为满足所谓Y2-condition的一些参数的选择。给出了对于一个非线性质量-弹簧-阻尼器系统的应用实例。
The stability analysis of a fuzzy-model-based nonlinear control system is presented, which consists of a nonlinear electrical drive plant and a nonlinear PD state feedback controller, and the design of the nonlinear gains of the controller is given. The nonlinear electrical drive plant is represented by fuzzy model proposed by Takagi and Sugeno and a nonlinear PD state feedback controller is designed to close the feedback loop.We introduce differential state feedback in fuzzy system for the first time and analyze the stability of the whole system efficiently. The design methodology finally comes down to the choice of some coefficients to satisfy so-called Y2-condition. An application example on stabilizing a nonlinear mass-spring-damper system will be given.
