| 中文摘要 |
| 众所周知，在分散控制系统的设计中，不稳定的固定模的存在使得我们不能用分散化的、定常的局部控制器去稳定系统。本文应用一种采样和具有指数衰减保持的时变控制器来消除系统的固定模，由此而得到的定常可稳定的系统可以用局部输出反馈来稳定并进而可以实现最优控制。 |

| In the design of decentralized control systems, it is we-ll knonwn that the existence of unstable fixed modes prevents us from stabilizing it via decentralized time-invariant local controllers. In this paper, the time-varying controllers employing samplers and holding devices with exponential decay are applied in local stations to eliminate the fixed modes of system. For this resultant time-invariant, stabilizable system, an optimal output feedback can be applied at local stations to stabilize the system and also achieve the optimal control. |
