| 摘 要： | 研究压电主动结构振动控制当中传感器／作动器的位置优化问题。从系统的状态空间方程出发，在系统可控性、可观性Grammian矩阵特征值的基础上来描述性能指标，以控制能量最小化和传感能量最大化作为优化目标，利用遗传算法（GE）进行优化计算，计算过程中对传感器／作动器的位置采用二进制编码加以描述。通过对一压电板结构的仿真计算对该方法进行了验证，优化计算结果与枚举法结果完全相符，从而证明了方法的有效性。

| Abstract: | The purpose of this paper is to investigate the optimal placement of piezoelectric sensor/actuator for active vibration control of smart structure. Base on the state space equation and the controllability/observability Grammian matrix, the optimal target was given by minimize the control energy and maximize the sensitive energy. The genetic algorism was used for optimal computation. The placements of sensor/actuator were defined with binary coding. A piezoelectric plate has been simulated to attest the optimal method. Validity has been proved because it obtained the same result for optimal method calculation and enumerate method calculation. |
