Optimized structure based on vibration active control circuit of distributed piezoelectric actuator and optimization method thereof

The invention relates to an optimized structure based on a vibration active control circuit of a distributed piezoelectric actuator. The structure comprises distributed piezoelectric actuators, a piezoelectric beam, and circuit structures; and the distributed piezoelectric actuators are connected with the circuit structures and the piezoelectric beam through wires. According to the structure, a pole direction of a piezoelectric actuator can be changed conveniently and a problem that a traditional actuator can not excite complicated vibration can be solved; therefore, the structure is an optimized one that has a novel design and can be widely applied to active control of a distributed piezoelectric actuator in practice. Besides, an active vibration control effect of a distributed piezoelectric structure is improved; and a multi-mode control can be realized by adjustment and increase or decrease of a circuit of the structure. In addition, the optimization method based on the vibration active control circuit of
