摘　　要：提出了一种简单新颖的水轮发电机组鲁棒控制器设计方法,并将其应用到一个高阶、非最小相位的水轮发电机组中.该方法的主要特点是被控对象的所有稳定控制器均可用两个独立的自由参数q1和q2来描述.以我国某水电站的真实数据对所设计的控制器进行计算机仿真.仿真结果表明:在系统参数发生变化的情况下,所提出的控制策略能保证水轮机调节系统获得鲁棒稳定性和良好的动态性能.In this paper, a novel simple controller design method for hydroelectric generating unit is described and applied in a high-order and non-minimumphase hydroelectric generating u- nit. The main characteristic of this method is that the set of all stabilizing controllers can be characterized by two free parameters q1 and q2. A hydropower station in China＇s real data on the controller designed was simulated. The simulation results show that： robust stability and good dynamic performance of the control system can be achieved by using the p strategy in the circumstances when system parameters have a change.
