| 摘 要： | 以独立模态空间控制的权矩阵元素为设计变量,根据求解结构/控制综合设计的多目标优化问题的Preto优化解的约束方法,建立了以ARE的解矩阵的迹为目标函数,以满足闭环系统之渐进稳定条件为约束的多目标优化模型.然后根据此权矩阵的优化解构造出耦合模态空间控制的权矩阵.由此可以使控制系统用较少的执行器对结构的多个模态进行控制并使被控系统满足给定的稳定条件与性能限制而且使性能指标极小化.对两个机敏柔性梁的计算机模拟结果验证了这一方法的有效性.

| Abstract: | By taking the weighting matrix elements under independent modal space control as design variables and applying Pareto's method of optimization to integrated design of structure/control, the target-functions are established according to the traces of ARE matrix to satisfy the multi-optimization model restrained by close loop system's requirement for progressive steadiness. The weighting matrix of dependent modal space control can then be built. Therefore, the control of more than one modes in system can be realized by using one actuator with the system performance features being excellent satisfying the specified stability. Computational results of two beams prove the efficiency of this approach. |
