Description
Summary:	Geometric nonlinearities of the beam and piezoelectric patch are considered. Velocity feedback control algorithm is implemented applying piezoelectric materials. The equation of motion of the system is established using Hamilton's principle. The effects of control gains on primary resonance properties of the beam are studied. It is observed that, with the amplitude of external excitation increasing, the amplitude of resonance curve increases. The velocity feedback control can improve unstable resonance of the beam. When the control gain is increased to a certain value, the unstable regions in the resonance and amplitude-frequency curves disappear.
