ILC Based Active Vibration Control or Smart Structures
Vibration control of flexible structures is observed to be a good way to maintain structural integrity as well as to optimize performance for space structures currently. Taking the piezoelectric flexible structure as research object, this paper focuses on the methodology and implementation of a vibration suppression system. An efficient method to simulate and analyze the piezoelectric plate is presented with ANSYS applied, while an iterative learning control (ILC) algorithm is proposed as the control strategy. A finite element model of the flexible plate is constructed by an APDL (ANSVS Parameter Design Language) program. By transient analysis of piezoelectric flexible plate, the models of the control channel and the primary path are obtained. Finally, an ILC based controller, having good cancellation of the vibration of the flexible plate, is developed. The ANSYS experiments suggest that analyzing the piezoelectric flexible plate by ANSYS is a cost-effective method. The SIMULINK results show that the open-loop PID-type learning algorithm is effective for the active vibration control.
