本文针对燃气轮机组本身技术高速发展与其主要系统控制方式相对滞后这一矛盾，将最优控制理论和非线性控制理论引入到燃气轮同步发电机的励磁控制系统中，特别考虑了作为原动机的燃气轮机的特性，提出了两种励磁控制策略：最优励磁控制和非线性励磁控制．通过分析与对比，并针对某一具体系统给出了非线性励磁控制器的详细设计，证明并特别指出该控制策略是可行和最佳的．
In view of the contradiction between the rapid development of gas turbine technology and its main system control method, the optimal control theory and nonlinear control theory are introduced into the excitation control system of gas-turbine synchronous generator. In particular, the gas turbine as the prime mover Two kinds of excitation control strategies are proposed: optimal excitation control and nonlinear excitation control. The detailed design of the nonlinear excitation controller is given through analysis and comparison and for a specific system, and the control strategy is proved and especially pointed out that the control strategy is feasible and optimal.
