Intelligent PID controller using iterative learning algorithm for active vibration controller of flexible beam

摘要

The simulation of proportional-integral derivative (PID) controller was performed within Matlab SIMULINK environment. Intelligent Iterative Learning Algorithm (ILA) was utilized to tune the parameters of PID controllers, Kp, Ki, Kd to control Active Vibration Controller (AVC) of flexible beam structure. The dynamic characteristics of flexible beam were identified using neural network algorithm. During the investigation the PID-ILA controller showed faster settling time than that of normal PID controller. PID-ILA also gave smaller mean square error of 9.34×10⁻⁴mm and compared to 5.9×10⁻³mm achieved using the normal PID.
