THE NUMRICAL ANALYSIS OF OPTIMAL CONTROL ON STRUCTURE DEFORMATION

Structure that can respond to enviroment appropriately by itself is calledsmart structure,e.g.plate containing piezoceramics. In this paper, FEM was formulatedhmeans of electro-mechanical variational equations and the procedure to get relationshipbetweell voltage on piezoceramic and structure deformation,i.e. control matrix,waJs alsoestablished.Using optimal method, optimal control of structure deformation was achievedwith consideration of no or some restricted conditions.
