| 摘 要： | 针对一类带有未知前件变量的T-S模糊系统,提出一种新的观测器-控制器设计方法.首先,在前件变量完全未知的情况下,将观测误差方程中由未知前件变量导致的相关项利用Lipschitz条件进行限制;然后,根据Lyapunov函数得到系统稳定性条件,同时提出一种基于特征值的矩阵缩放方法和一种基于模糊 Lyapunov 函数的高增益观测器方法计算观测器-控制器的增益矩阵;最后,针对动力定位船舶的控制问题对两种方法进行仿真验证和比较分析,以表明所提出方法的有效性.

| Abstract: | For the T-S fuzzy system with unknown premise variables, a new observer-controller design method is proposed. While the premise variables are all unknown, the terms caused by the unknown premise variables in observer error equations are restricted by the Lipschitz conditions. Then, the system stability conditions are obtained based on the Lyapunov function method, and an eigenvalue matrix scaling method and a fuzzy Lyapunov function high gain observer method are proposed to calculate the observer-controller gains. Finally, based on the above two approaches, ship dynamic positioning simulation results are compared and analyzed, which show the effectiveness of the proposed methods. |
