基于模糊自整定PID的原点反共振振动筛振幅控制

针对原点反共振振动筛在反共振点附近工作时振幅不稳定的问题，应用模糊自整定PID控制策略对其振动系统进行了控制。设计了模糊自整定PID控制器的结构，确定了隶属函数和模糊规则，给出了反模糊化方法。仿真研究结果表明，原点反共振振动筛的振幅得到了很好的控制。

Amplitude Control for a Driving Point Antiresonant Vibrating Screen Based on Fuzzy Self-tuning PID Control

Aiming at the problem that the amplitude of the driving point antiresonant vibrating screen is unstable when it is working nearby the antiresonance point,fuzzy self-tuning PID control strategy is applied to control the vibration system.Moreover,the structure of fuzzy self-tuning PID controller is designed,the membership functions are determined,and the fuzzy rules and the defuzzification rules are given.Simulation results show that the amplitude of the driving point antiresonant vibrating screen is in well ...
