摘要: 首先综述代数 Riccati 方程解的存在性条件, 然后对于该方程存在唯一正定最优解的充分必要条件给出严格证明. 最后利用这一条件, 纠正了鲁棒分散控制器设计中的一些错误结果.Abstract: First, the existence conditions on the solutions to the algebraic Riccati equation are reviewed. Then, a strict proof is presented for a necessary and sufficient condition on the existence of a unique optimal positive definite solution to this equation. By using this condition, some untrue results on the design of robust decentralized controllers are corrected.
