针对一类具有范数有界参数不确定性的多输入模糊双线性系统,在系统的状态不完全可测的情况下,提出一种模糊镇定控制方法。设计模糊观测器估计系统的状态,基于模糊观测器,设计模糊控制器保证闭环系统的渐近稳定性。模糊控制器可以通过求解线性矩阵不等式(LMI)求得。仿真示例验证了设计方法的有效性。
For a class of multi-input fuzzy bilinear systems with norm-bounded parameter uncertainty, a fuzzy stabilization control method is proposed when the state of the system is not completely measurable. The fuzzy observer is designed to estimate the state of the system. Based on the fuzzy observer, the fuzzy controller is designed to ensure the asymptotic stability of the closed-loop system. Fuzzy controller can be solved by solving linear matrix inequality (LMI). Simulation examples verify the effectiveness of the design method.
