摘    要:提出了一种优化非线性系统控制参数的方法——回归正交试验法。该方 法运用正交试验原理安排一定的试验次数,再将试验结果用最小二乘法进行拟合,在控制参 数与目标函数间建立起回归经验公式,利用该经验公式对整个系统的动态性能进行预测和控 制。该方法已应用于水轮机调速系统控制参数的优化,仿真结果表明其优化效率高,提高了 系统的动态品质。

关 键 词:正交试验法    回归分析    水轮机调节系统

Abstract:The regression orthogonal test approach can be used to optimize the control parameters for nonlinear systems. Because in this approach the orthogonality is used for rational arrangement of the test, the number of the tests is greatly reduced. Then the least square method is adopted to establish the regression function between the control parameters and the objective function. Based on the regression empirical function, the dynamic performance can be predicted and controlled. This method has been applied to the optimization of the control parameters of a water turbine governing system and the simulation results show the method is effective.
Keywords:orthogonal test approach  regression analysis  water turbine governing system
