摘　　要：针对大型水轮发电机调速控制器,提出了非线性自适应控制设计方法。首先,建立含有未知参数的非线性数学模型,其次通过递推设计方法得到了自适应控制策略,而且在策略中包含了对未知参数的动态估计,最后获得了水轮机调速器的自适应分散镇定控制策略。在控制策略中所有的变量都是可量测的,并且控制策略具有分散性和适应性。计算机仿真研究结果证明了水轮发电机调速控制器的自适应控制策略的有效性。A design approach to nonlinear adaptive decentralized control system is developed for large-scale hydraulic turbine generator governor. The nonlinear mathematic model with unknown parameters is set up and the adaptive control strategy is then formed by the adaptive back-stepping design method,in which a dynamic parameter estimator is involved. A general expression of non-linear adaptive decentralized governor control strategy is thus obtained,in which all of the feedback variables are local measurements. The simulative results on a one-machine-infinite-bus system manifest its validity.
