A Nonlinear Unified Controller Design for Heavy-Duty Turbogenerator

采用非线性直接反馈方法来处理大型汽轮发电机组的综合控制器设计 .将调速与调压综合于一体 ,用 DFL方法实现非线性受控对象的线性化 ,配合 L Q最优化设计所得到的综合控制器由完全线性化的补偿器和鲁棒最优输出反馈控制器组成 ,经单机 -无穷大母线系统的数字仿真 。

The method of DFL was applied to design a nonlinear unified contr oller for heavy duty turbogenerator. Considering adjustment of speed and voltag e, by using the DFL method which linearizes the nonlinear object and by LQ optio nal controlling design, the control system consists of co mplete linearization compensator and optional output feedback controller. The di gital simulation results for synchronous machine against an infinite bus power s ystem show that the nonlinear unified controller can improve the stability of t ransmission system greatly.
