基于自校正PID控制的智能悬臂梁振动控制
Vibration Control of Smart Cantilever Beams based on Self-tuning PID Control
摘要
Abstract
Because of the variable working environment of the intelligent structures, the performance parameters will also change. The previously built model may not be adaptable any longer to the preset control law. This paper applies the characteristics of the driving-sensing integration of the piezoelectric bimorph to realize the adaptive control research of smart cantilever beams. Based on the pole assignment theory, the self-tuning PID control method is used to design the on-line control parameters to solve the problem that the model parameters cannot be updated in real time and the control precision is low. At the same time, the effect of the general PID control based on Neigler-Nicholes parameter tuning method is compared with that of the self-tuning PID control method. Through the numerical simulation based on MATLAB/SIMULINK and experimental verification, the control results of the two control methods are compared. It is shown that the self-tuning PID control is more effective. The free vibration of the smart cantilever beam is effectively controlled by using the driving-sensing characteristics of the piezoelectric bimorph. This study provides a theoretical and experimental basis for vibration absorption and vibration reduction of smart structures.关键词
