摘　　要：建立了水轮机调节系统被控对象的非线性模型,用递推最小二乘法(RLS)对被控对象进行参数辨识。仿真实验证明,该模型与被控对象模型相吻合、过程简单、效果良好、易于实现编程。基于此对控制参数进行了优化,改善了系统的动态品质。具有实用价值。For better control of the hydro turbine generating units, it is desirable to identify the model of the subject of the hydro turbine governing system before optimizing its control parameters. The nonlinear model of the hydro turbine governing system is established first. Its parameters are identified with the Recursive Least Square method （RLS）. The simulation experiments demonstrate that the difference between the identified model and the real one is rather small. The method is simple, effective and easy to implement. The optimization of the control parameters can be further made based on the identified model to improve the dynamic performance. Therefore it is valuable and practical.
