摘要：This paper focuses on the design problem of shape control of composite
   plate using piezoelectric stiffeners, and the optimum shape control with
   limited independent controlling parameters is investigated. The
   parametric description of linkage between the actuators and signal
   generators (independent control parameters) is presented and a
   concurrent design methodology of actuator linkage and control parameters
   is developed. To deal with the special optimization problem with
   discrete variables (description parameters of linkage) and continuous
   variables (controlling parameters) coexisted, an optimization scheme
   composed of Genetic Algorithms and Linear Least Square Method is
   developed. An adhesive element is used to formulate the connection
   between the PZT stiffeners and the host composite plate in the present
   finite element analysis model. The effectiveness of the present design
   methodology and optimization scheme is then demonstrated through
   numerical examples for shape control of composite plate.
