Multimode vibration supression of piezoelectric plate based on minimal control synthesis algorithm

In order to suppress the vibration of piezoelectric plate effectively, the minimal control synthesis (MCS) algorithm based on Popov's criterion method is used to suppress vibration of a simple plate. The state equations of piezoelectric plate first-order and second-order mode are set up by experiment. The reference model is determined by LQR method. Simulation results show that the method have faster convergence, good robustness performance and strong anti-interference ability whether transient disturbances excitation or persistent disturbances excitation.
