摘要:

本文给出了一类双曲型偏微分方程(PDEs)次优$H^\infty$控制问题的解法。本文首个结果表明,所考虑的这类PDEs可等价表示为无穷维离散时间系统。利用这一特性,本文证明求解该次优$H^\infty$控制问题等价于求解一个有限维离散时间系统的对应问题,该系统的矩阵由PDEs推导而来。在求解这个简单得多的问题后,可轻松推导出原问题的解。具体而言,次优$H^\infty$控制问题的最优补偿器解由一组在边界处受驱动和观测的双曲型PDEs描述。我们通过一个边界控制、边界观测的振动弦示例验证了研究结果。

英文摘要:

A solution to the suboptimal $H^\infty$-control problem is given for a class of hyperbolic partial differential equations (PDEs). The first result of this manuscript shows that the considered class of PDEs admits an equivalent representation as an infinite-dimensional discrete-time system. Taking advantage of this, this manuscript shows that it is equivalent to solve the suboptimal $H^\infty$-control problem for a finite-dimensional discrete-time system whose matrices are derived from the PDEs. After computing the solution to this much simpler problem, the solution to the original problem can be deduced easily. In particular, the optimal compensator solution to the suboptimal $H^\infty$-control problem is governed by a set of hyperbolic PDEs, actuated and observed at the boundary. We illustrate our results with a boundary controlled and boundary observed vibrating string.
