混合动态系统的模糊接口设计

Fuzzy Logic Based Interface Design of Hybrid Dynamical System

利用模糊逻辑控制的思想 ,给出了混合系统的模糊接口设计 .该接口通过其内部参数的学习把连续状态空间划分成多个子空间 ,使受控对象的非线性系统在每个子空间内可由一基于模糊逻辑的线性模型逼近 ,从而简化了对象模型和设计任务 .当连续状态穿越空间边界时 ,则由上层离散事件控制器进行模式切换 。

By means of the ideal of fuzzy logic based control, a fuzzy interface for hybrid systems was presented. The fuzzy logic interface partitions a continuous state space into a finite number of regions, where by the nonlinear controlled plant can be approximated by a linear model based upon fuzzy logic in each region, which simplifies the plant model as well as design task. When the continuous state hits the boundary of two regions, the high level supervisor issues a command to execute mode switching, therefore the hybrid system runs in a stable and safe manner.
