本文提出的 MIMO 控制器同时确定多个执行器、传感器和适当的输出反馈增益的最佳放置。控制器设计是在数字域中进行的，因此在实现阶段通常可以使用较低的采样率。采用指数惩罚系统持续状态的方法，可以在存在外部干扰的情况下获得更快的稳定时间。在优化中明确考虑了由于力/行程限制而与执行器饱和相关的非线性。该算法不需要模态形状的闭合形式表达式。因此，它适用于更广泛的不易落入任何规则几何形状的二维结构。
The MIMO controller proposed in the paper simultaneously determines optimal placements for multiple actuators, sensors and appropriate output feedback gains. The controller design is carried out in the digital domain hence typically lower sampling rates can be used at the implementation stage. A method of exponentially penalizing the persistent states of the system is used to obtain faster settling times in the presence of external disturbances. The nonlinearities associated with actuator saturation due to force/stroke limitation is considered explicitly in the optimization. The algorithm does not require closed form expressions for modal shapes. Hence it is applicable to a wider class of 2D structures that do not readily fall into any regular geometric shape.
