| Abstract: | According to the Hamilton principle,the equation of vibration control of composite laminated plates with the simply supported boundary condition using various plate theories is deduced,and the frequency and amplitude of the system are gained.Then according to the energy criterion the weight coefficient matrix Q and R in using the linear quadratic regulator method are given.Through solving the Riccati equation,the displacement and control force are obtained.Simulation analysis of the system is carried out by using the Mathematic program,and the effects of various factors on the vibration control of the system are analyzed.The results are useful to the vibration control and optimization of the system. |
