摘　　要：将直接反馈线性化理论运用于汽轮发电机组快速汽门控制的设计中,得到了实用的非线性快速汽门控制规律。在此基础上,提出了一种对反馈测量通道故障具有鲁棒容错性的大范围线性化最优快关控制系统设计方法。所设计的系统实现了大范围稳定。并且由于采用对测量通道容错的完整性设计方法,提高了系统的可靠性。又由于采用多回路同时镇定方法,也提高了系统在测量通道发生故障下的动态特性。The application of direct feedback linearization to stream turbine-generator fast valving control is studied in this paper, and practical fast valving control law is achieved. Furthermore, this paper presents an approach for designing optimal fast valving control system with fault-tolerance and robust performance to sensor failure in the feedback signal channel via large-scale linearization. The control system with large-scale stability is designed. And the systems reliability is improved because of application of integral design method to sensor failure in the feedback signal channel. The systems dynamic characteristic to sensor failure in the feedback signal channel is also improved because of application of the multiloop Simultaneous Stabilization method.
