时滞系统的模糊反馈推断控制器设计

The Design of Fuzzy Feedback Inferential Controller for Time-delay Systems

针对主要输出可直接测量的时滞系统,提出一种模糊反馈推断控制器。该控制器是在典型推断控制的基础上进行简化和改进,并用模糊逻辑和推理来自适应地调节控制器的滤波器时间常数。系统性能分析及仿真实验结果表明该控制器对带有随机扰动的时滞系统具有良好的控制性能。

A kind of fuzzy feedback inferential controller is proposed to the systems whose main output variables are measurable. The controller is derived from the simplification and improvement of the typical inferential controller, and in which fuzzy logic and inference are used to adjust its filter time constant adaptively. The system performance analyses and simulating experiment results show that the controller has good control performance to the time-delay systems with random disturbances.
