| 摘 要： | 提出了定性变量及定量变量的新概念,并将二者的综合集成推理应用到单输入模糊控制器的设计之中.将定性变量作为判断条件随时判断系统的动态特性,定量变量作为唯一的输入变量,可以有效地减少模糊控制规则的数量,同时保证被控对象具有优良的动态性能.将耗散结构理论应用于模糊系统的稳定性分析之中,从能量衰减的角度分析了系统稳定的本质.

| Abstract: | The quantitative and qualitative variables are introduced in this paper, and the synthetically combined reasoning of them is applied in the design of single-input fuzzy controller. Qualitative variable is used to estimate the dynamical property of the system as a judging term, and quantitative one is employed as the only input. Using this method, the controlling rules are reduced effectively and the dynamic property of the system is guaranteed. The dissipation theory is used in the stabilization analysis of system in view of the energy attenuation. |
