本文的目的是简要地说明跟踪控制问题与执行器饱和，简要回顾当前的文献，并制定了问题在手动（飞行）控制的背景下。通过一个简单的例子说明了饱和跟踪控制的复杂性。提出了一种同时具有速度和幅度约束的手动飞行控制问题的新方法，即线性二次跟踪（LQT）。该方法专门针对受位移和速率执行器约束的动态跟踪控制问题，特别是针对开环不稳定对象的挑战性情况，这是当前飞行控制的兴趣所在。同时，由于在飞行控制中使用的简化植物模型的低阶，因此可以合理地假设全状态反馈是可用的，尽管跟踪的变量是一个标量，例如俯仰率。通过一个简单的例子证明了所提出的LQT解决方案的饱和避免方面。
The objectives of this article are to concisely state the tracking control problem with actuator saturation, briefly review the current literature, and formulate the problem in a manual (flight) control context. The complexity of tracking control with saturation is demonstrated via a simple example. A new approach to the manual flight control problem with both rate and amplitude actuator constraints, referred to as linear quadratic tracking (LQT), is outlined. This approach is specifically directed toward the dynamic tracking control problem subject to both displacement and rate actuator constraints, particularly for the challenging case of open-loop unstable plants, which are of current interest in flight control. At the same time, due to the low order of the simplified plant models used in flight control it is reasonable to assume full state feedback is available, although the tracked variable is a scalar, e.g., pitch rate. The saturation avoidance aspect of the proposed LQT solution is demonstrated for the simple example.
