| 摘 要： | 三容水箱是较为典型的非线性时延对象,常规PID控制难以取得理想的控制效果,本文结合非线性模型线性化方法、PID控制结构及基于T-S模型的模糊控制技术,提出了基于T-S模型三容水箱的模糊PID控制策略.这种策略根据液位变化,通过适用度加权产生PID控制参数,可实现参数的平稳过渡,有利于改善控制性能.仿真结果验证了控制策略的有效性和正确性.

| Abstract: | It is difficult for the conventional PID to effectively control three-tank water which represents a typical plant with non-linearity and large time delay.By combining the linearization method for non-linear plant,PID control structure and fuzzy control based on T-S model,the fuzzy PID control of three-tank water based on T-S model is devised.The strategy aims at improving the control performance of the three-tank water by weighing the membership function to produce PID parameters and,thus,making parameters vary steadily with the variation of water level.Simulation results show that the control strategy proposed in this paper is correct and effective. |
