控制器状态和参考调速器（CSRG）是一个附加计划的标称闭环系统的动态控制器，监督控制器的内部状态和参考输入到闭环系统，以执行逐点的时间约束。通过承认控制器状态和参考修改，CSRG可以实现一个扩大的约束域的吸引力相比，传统的参考总督计划，只允许参考修改。本文研究了具有随机干扰和机会约束的系统的CSRG。我们描述了CSRG算法在这样一个随机设置，并分析其理论性质，包括机会约束的强制执行，有限时间参考收敛，闭环稳定性。我们还提出的例子说明CSRG约束飞机飞行控制的应用。
The controller state and reference governor (CSRG) is an add-on scheme for nominal closed-loop systems with dynamic controllers which supervises the controller internal state and the reference input to the closed-loop system to enforce pointwise-in-time constraints. By admitting both controller state and reference modifications, the CSRG can achieve an enlarged constrained domain of attraction compared to conventional reference governor schemes where only reference modification is permitted. This paper studies the CSRG for systems subject to stochastic disturbances and chance constraints. We describe the CSRG algorithm in such a stochastic setting and analyze its theoretical properties, including chance-constraint enforcement, finite-time reference convergence, and closed-loop stability. We also present examples illustrating the application of CSRG to constrained aircraft flight control.
