论文摘要
我们研究了由于通信网络中的非理想性在微小启发方面,数据包辍学对最佳派生控制器和观察者的性能的影响。这些数据包辍学是通过有向图的离散约束开关信号来建模的。我们考虑时间最佳控制和估计,最低能量和燃料优化以及对数据包辍学的系统问题的问题,这些问题被证明是组合的;并从这些优化问题的最坏情况下计算算法。为了减轻解决这些组合问题的计算负担,对切换信号施加了部分顺序。对所提出的方法的验证是在一组随机生成的系统上完成的。最后,通过将每个最佳控制问题的最佳案例性能与基础网络相关联,可以在一组可用的通信网络之间进行优化。
We investigate the impact of packet dropouts due to non-idealities in communication networks on the performance of optimally derived controllers and observers in a minimax sense. These packet dropouts are modeled by discrete constrained switching signals via directed graphs. We consider time optimal control and estimation, minimum energy and fuel optimization and LQR problems for systems subject to packet dropouts which turn out to be combinatorial; and compute algorithmically the worst case performance of these optimization problems. To reduce the computational burden in solving these combinatorial problems, a partial order is imposed on the switching signals. Validation of the proposed methods is done over a set of randomly generated systems. Finally, by associating the worst case performance for each optimal control problem to the underlying network, one can optimize among the set of available communication networks.
