Static Shape Control of Adaptive Structure Using Composite Laminated Piezoelectric Element

The static shape control of composite plate adaptive structure was studied. Using the piezoelectric composite laminated plated element, the displacement sensitivity matrix was established. Then,the optimal control equations were derived from the sensitivity matrix. If there were same number of controlled displacements and actuators,the voltage of actuators could be obtained precisely by calculating linear equations. When the number of actuators was less,optimal methods were used,and the equations could be solved to achieve the optimal shape control of adaptive structure. Numerical example were given to compare the different control situations, and the results showed the efficiency of the method and the importance of actuators placement.
