研究了当某些传感器和执行器发生实时故障时控制系统的可靠镇定问题。使用控制器分解使得当其中一个控制器不再工作时仍能保持闭环稳定性。该工作是基于可以使用分散反馈稳定的对象的特征和所有稳定分散控制器的参数化。本研究还将因式分解理论扩展到非线性系统的分析与综合中，这是一般理论难以发展且扩展将是间接的。

The research deals with reliable stabilization of control systems when some of the sensors and actuators fail in real-time. Controller decomposition is used so that closed-loop stability is still maintained when one of the controller is no longer operational. The work is based on characterization of plants which can be stabilized using decentralized feedback and parameterization of all stabilizing decentralized controllers. The research will also extend factorization theory to the analysis and synthesis of nonlinear systems, where general theory is difficult to develop and the extensions will be indirect.
