摘要： 针对一类非线性不确定连续系统,在用T-S模糊系统对未知函数进行逼近的基础上,利用系统的耗散理论,系统地提出了一种模糊自适应鲁棒控制算法的综合方法,所提出的算法不仅使自适应学习参数的数目减少至最低,便于工程实现,而且还确保闭环系统渐近稳定。最后以船舶减摇鳍非线性控制系统为例,进行了模糊自适应鲁棒控制器的设计,经仿真研究表明,所提出的算法是有效的。

Abstract: A new fuzzy adaptive robust control algorithm is presented for a class of uncertain nonlinear systems. In the algorithm, Takagi-Sugeno-type fuzzy logic systems are used to approximate unknown functions in the systems, and the adaptive mechanism with minimal learning pa-rameterizations can be achieved by using the dissipative system theory. An example illustrating the method of ship roll stabilization by the fin control system is included. It is shown that the designed system can guarantee the performance of the global asymptotic stability.

Key words: dissipation theory, adaptive robust control, fuzzy control, ship roll stabilization
