    本文首次用非线性大范围直接反馈方法来处理大型气轮发
     电机组综合控制器设计。首先介绍了国内外对输电系统稳定性
     的处理方法。给出了适用于工程应用的全局线性化的实用模型。
    指出了选择具工程物理背景状态基的技巧,以此首次将调速与
    调压综合于一体,并有DFL方法来实现非线性受控对象的线
    性化。配合LQ最优化设计,所得到的综合控制器由完全线性植
    化补偿器和鲁棒最优输出反馈控制器组成。本文还首次将DFL
    方法与局部线性化方法结合起来,对Vt进行处理,由此得到
    了基于机端电压Vt负反馈的综合控制器,更具工程意义。
    最后,就单机——无穷大母线系统所作的数字仿真表明这种
    新型非线性综合控制器的确综合了各类控制器的优点于一身,
     对提高输电系统稳定性方面具有一系列突出的优越性 [英文摘要]:     It is the first time to apply the non-linear direct Feedback method to design the centrol system of large steam turbine generator.
    First of all, introduce various methods of control system in power station domestically and abroad.
    Then explain mathematic model of application in engineering by DFL method dealing with mult-input/ output out lining the style of selecting state variables on the background of engineering physics.
    Base on all that metioned above, Considering adjustment of speed and voltage and non-linear model of controlled object, using the DEL method which completes the design of comprehensive control system and LQ optional controlling design, therefore the control system has the characteristics of consisting of complete linearization compensator and optional output Feedback contoller.
    It is also the first time to Combine the DFL method and Local Linearization to deal with different non-linear physical vector. So the comprehensive control system having terminal voltage Feedback is more practical comparatively.
    The results of synchronous machine against an infinite bus system digital simulation states that the comprehensive control system does have the key function of combining the characteristics of other control system. So it enhances the stability of power supplying system.
