| 摘 要： | 所研究的纯滞后系统控制器是将模糊控制与PID控制规律融为一体而形成的Fuzzy-PID控制器。此控制系统是一种两层式控制系统,PID控制使得控制简单易操作,而模糊调节系统又使系统响应快、超调小,其参数设定无需知道被控对象的具体参数及数学模型,对不同的对象具有适应性。介绍了Fuzzy-PID控制器的构成并推导出了相关的数学公式。论文结尾给出了仿真实例,仿真结果表明这种方法具有良好的鲁棒性,对时滞系统非常有效。

| Abstract: | Introduces an effective control method of time delay system based on fuzzy control theory.The main contents are adjusting proportion-integral-differential(PID) parameters using fuzzy logic method.The system has two layers,one is the PID adjuster that makes the system be easy operation,the other is fuzzy adjuster that makes the system be quick response and small overshoot.The advantage is that the system does not need to know precise mathematics model of controlled object,so it could be applied for different objects.The paper presents the construction of the fuzzy-PID controller and some related equations.At the end of the paper,computer simulation is given.The simulation results indicate that this method has good robustness and validity to the time delay system. |
