一致最优控制问题是在线性时变离散时间系统的背景下提出的，控制器在一组预先指定的外部信号上一致最优。证明了最优控制器的存在性，并导出了最小代价的计算公式。在频域中处理时不变的情况。结果表明，对于时不变系统，最优时变控制器并不比最优时不变控制器好。
The problem of uniformly optimal control is posed in the context of linear time-varying discrete-time systems; the controller is optimal uniformly over a pre-specified set of exogenous signals. Existence of an optimal controller is proved and a formula for the minimum cost is derived. The time-invariant case is treated in the frequency domain. It is shown that for time-invariant systems an optimal time-varying controller is no better than an optimal time-invariant controller.
