我们考虑在连续时间内随时间变化的执行器位置,目标是最大程度地提高grammian的可控性痕迹。该问题的自然放松是允许二进制{0,1}变量指示在给定时间使用执行器以在闭合间隔[0,1]中使用值。我们表明,原始问题和放松问题的所有最佳解决方案都可以通过明确的公式给出,并且,只要输入矩阵没有零列,原始问题的解决方案集合的解决方案集合。
We consider the time-varying actuator placement in continuous time, where the goal is to maximize the trace of the controllability Grammian. A natural relaxation of the problem is to allow the binary {0, 1} variable indicating whether an actuator is used at a given time to take on values in the closed interval [0, 1]. We show that all optimal solutions of both the original and the relaxed problems can be given via an explicit formula, and that, as long as the input matrix has no zero columns, the solutions sets of the original and relaxed problem coincide.
