Abstract

This letter considers the design of sparse actuator schedules for linear time-invariant systems. An actuator schedule selects, for each time instant, which control inputs act on the system in that instant. We address the optimal scheduling of control inputs under a hard constraint on the number of inputs that can be used at each time. For a sparsely controllable system, we characterize sparse actuator schedules that make the system controllable, and then devise a greedy selection algorithm that guarantees controllability while heuristically providing low control effort. We further show how to enhance our greedy algorithm via Markov chain Monte Carlo-based randomized optimization.
具有可控性保证的线性系统的点状稀疏执行器调度
这封信探讨了线性时变系统的稀疏执行器计划的设计问题。执行器计划表为每个时间瞬间选择在该瞬间对系统起作用的控制输入。我们要解决的问题是,在每次可使用的控制输入数量受到硬约束的情况下,如何优化控制输入的调度。对于稀疏可控系统,我们描述了使系统可控的稀疏执行器调度,然后设计了一种贪婪选择算法,在保证可控性的同时,启发式地提供了较低的控制努力。我们进一步展示了如何通过基于马尔科夫链蒙特卡罗的随机优化来增强我们的贪婪算法。
