ABSTRACT This paper addresses a continuous-time preview control problem in output feedback setting. By a state transformation approach, it is shown that the optimal output feedback law is implemented in two different ways. The first and second implementations have the structures similar to the Smith and observer-based predictors for input-delay systems, respectively. In order to illustrate the features of the optimal control law, we design an Load Frequency Control system, which utilises load demand prediction. Although the accompanying prediction error obstacles the performance improvement, it is demonstrated that the adverse effect is mitigated by the weighting function technique.

关于$H^2$预览输出反馈律的实现，并应用于带负载需求预测的LFC

摘要 本文解决了输出反馈设置中的连续时间预览控制问题。通过状态转换方法，表明最优输出反馈法则以两种不同的方式实现。第一个和第二个实现的结构分别类似于用于输入延迟系统的 Smith 和基于观察者的预测器。为了说明最优控制规律的特点，我们设计了一个利用负荷需求预测的负荷频率控制系统。虽然伴随的预测误差阻碍了性能的提高，但事实证明，加权函数技术减轻了不利影响。
