| 摘 要： | 研究了空间智能桁架振动控制中的作动器／传感器位置优化问题。在对作动器／传感器进行动力学建模的基础上，推导出整个空间桁架机电耦合作动方程和传感方程。基于作动效率和观测效率，提出了不依赖于控制方法的位置优化准则，采用遗传算法对作动器／传感器位置进行了优化。最后针对空间智能桁架进行了位置优化仿真和模糊振动控制仿真，仿真结果验证了遗传算法优化此类问题的优越性、可信性。

| Abstract: | The problem of optimizing the location of piezoelectric actuators/sensors was studied in this paper. Theoretical modeling of the vibration of a space smart truss with piezoelectric actuators/sensors was presented. Genetic algorithms had been used to optimize the location of actuators and sensors. The best location was determined with the efficiency of actuating and observation. This method was independent of the control gains. Finally, the simulations of placement optimization and fuzzy vibration control of a space intelligent truss were studied. Result shows genetic algorithm is effective and believable for this problem. |
