Abstract

This paper discusses the [Formula: see text] preview control problem for a class of continuous-time systems with actuator saturation. Firstly, an integrator auxiliary variable is introduced to merge the preview compensation term based on the future reference trajectory to the state variable of error system (ES). The tracking control problem is transformed into a standard [Formula: see text] controller design problem. Meanwhile, the indirect function of the actuator saturation is employed to overcome the saturation constraint in the closed-loop system. By using Lyapunov function and linear matrix inequality (LMI), the exist conditions of controller are established. And for the original system, the tracking controller with preview action is designed. Finally, an example on an L-1011 aircraft is given to show the effectiveness and superiority of recommended strategy in tracking and saturation control.

一类具有执行器饱和的连续时间系统的 H∞ 预览控制

本文讨论了一类具有致动器饱和的连续时间系统的[公式：见正文]预览控制问题。首先，引入一个积分器辅助变量，将基于未来参考轨迹的预览补偿项与误差系统（ES）的状态变量合并。跟踪控制问题被转化为标准[公式：见正文]控制器设计问题。同时，采用执行器饱和的间接函数来克服闭环系统中的饱和约束。利用 Lyapunov 函数和线性矩阵不等式（LMI），建立了控制器的存在条件。针对原始系统，设计了具有预览作用的跟踪控制器。最后，以一架 L-1011 飞机为例，说明了推荐策略在跟踪和饱和控制方面的有效性和优越性。

The Journal of Systems and Control Engineering refleSystems and control studies provide a unifying framework for a wide range of engineering disciplines and industrial applications. The Journal of Systems and Control Engineering reflects this diversity by giving prominence to experimental application and industrial studies. "It is clear from the feedback we receive that the Journal is now recognised as one of the leaders in its field. We are particularly interested in highlighting experimental applications and industrial studies, but also new theoretical developments which are likely to provide the foundation for future applications. In 2009, we launched a new Series of "Forward Look" papers written by leading researchers and practitioners. These short articles are intended to be provocative and help to set the agenda for future developments. We continue to strive for fast decision times and minimum delays in the production processes."
