我们引入了线性控制系统中的最小执行器位置问题,使得在保证可控性的同时,满足给定状态转移的最小控制努力的一个界。我们首先证明这是一个NP-难问题,遵循Olshevsky [1]最近的工作。接下来,我们证明了这个问题有一个超模结构。之后,我们提供了一个有效的算法,近似到一个乘法因子O(log n),其中n是多智能体网络的大小,任何最佳的执行器集,满足指定的能量标准。此外,我们表明,这是最好的近似因子,可以实现在多项式时间的最坏情况。最后,我们在大型Erdo-Rényi随机网络上测试了该算法,以进一步证明其效率。
We introduce the problem of minimal actuator placement in a linear control system so that a bound on the minimum control effort for a given state transfer is satisfied while controllability is ensured. We first show that this is an NP-hard problem following the recent work of Olshevsky [1]. Next, we prove that this problem has a supermodular structure. Afterwards, we provide an efficient algorithm that approximates up to a multiplicative factor of O(log n), where n is the size of the multi-agent network, any optimal actuator set that meets the specified energy criterion. Moreover, we show that this is the best approximation factor one can achieve in polynomial-time for the worst case. Finally, we test this algorithm over large Erdös-Rényi random networks to further demonstrate its efficiency.
