时滞系统的模糊自适应PID控制研究

Fuzzy Adaptive PID Control of a Time-delay System

将模糊控制和常规PID控制相结合,设计了一种模糊自适应PID控制器,该控制器根据偏差和偏差变化率的要求实时调整PID参数。通过仿真表明:该控制器既具有常规PID控制器高精度的优点,又具有模糊控制器快速、适应性强的特点,并可以迅速消除系统误差,保证了系统具有良好的动、静态特性。

This paper presents a fuzzy adaptive PID controller, where the parameters of PID are adjusted according to the error and its derivative： It possesses both the precise character of the PID controller and the flexible advantage of the fuzzy controller, and can guarantee good dynamic and static performance.
