| 摘 要： | 针对具有外部持续扰动的线性系统，研究前馈-反馈最优控制律的设计问题。给出了最优控制律的存在唯一性条件。并提出了最优控制律的设计算法。利用滤波器解决了前馈控制的物理不可实现问题。仿真结果表明，此算法易于实现，与传统的反馈最优控制相比对抑制外部扰动具有较强的鲁棒性。

| Abstract: | The design problem of a feedforward and feedback optimal control law is studied for linear systems affected by additive persistent disturbances. The conditions of existence and uniqueness of the optimal control law is given and an algorithm of solving the optimal control law is proposed. By using a filter the physically unrealizable problem of the feedforward control is realized. Simulation results show that the algorithm is easy to realize and, compared with the classical feedback optimal control law, is robust with respect to external disturbances. |
