提出了一种新的基于不变性原理的全局线性化控制方法，并将其运用于汽轮发电机组的快关控制系统中。此方法克服了普通最优快关控制系统存在的故障初期严重模型失配问题，实现了大范围的稳定，减小了阀门位移限幅特性对系统的影响。仿真结果表明，按这种方法所设计的系统有明显的优越性。
A new global linear control method based on the invariance principle is proposed and applied to the fast-closing control system of turbo-generator. This method overcomes the problem of serious model mismatch in the initial fast fault control system of the ordinary optimal fast-closing control system, realizes a wide range of stability and reduces the impact of the valve displacement limiting characteristic on the system. The simulation results show that the system designed by this method has obvious advantages.
