document: Active vibration control of piezolaminated smart beams This paper deals with the active vibration control of beam like structures with distributed piezoelectric sensor and actuator layers bonded on top and bottom surfaces of the beam . A finite element model based on Euler-Bernoulli beam theory has been developed . The contribution of the piezoelectric sensor and actuator layers on the mass and stiffness of the beam is considered . Three types of classical control strategies , namely direct proportional feedback , constant-gain negative velocity feedback and Lyapunov feedback and an optimal control strategy , linear quadratic regulator -LRB- LQR -RRB- scheme are applied to study their control effectiveness . Also , the control performance with different types of loading , such as impulse loading , step loading , harmonic and random loading is studied
