燃气轮机控制参数最优化分析研究

An Analytical Investigation on the Optimization of Control-Parameters for Gas Turbine

本文首先提出了一种单调控制理论。推导了单调控制的一些有关定理,发现在符合单调控制的情况下,可以方便地求出动态系统的最优决策序列,从而可以获得该系统的最优状态轨线。用该理论来求解燃气轮机系统时间最优控制问题的实践时,不仅工作量大幅度减少,而且可保持较高的精度。这对高性能燃气轮机和先进控制系统的设计都有较大的现实意义和使用价值。

In order to provide a tool in designing high-performance gas turbine, a monotonic control theory together with six relevant theorens are first propored in this paper. For a complicated dynamic system, it is possible to determine the optimal decision sequence, thereby to obtain the optimal state trajectory for the system. The optimal accelerating time may be approximated step by step without any appreciable error by plotting η versus t curve. Compared with other methods, the amount oi working quantity of monotonic control theory is much less and the accuracy is higher. It seems that the proposed monotonic control theory provides a realistic and practical tool for gas turbine designer.
