中文摘要 | Based on a kind of nonlinear robust control theory, this paper presents an optimum nonlinear controller for a class of SISO affine nonlinear systems. In order to obtain desired dynamics, the controller parameters are optimized based on genetic algorithms according to the specified performance indices. The controller designed for the non-elastic water hammer model is applied to the elastic one. Results are compared with the exact feedback linearization design. This proposed nonlinear controller demonstrates not only better adaptability against changes of model and parameters, but also excellent dynamic performance against three-phase short circuit fault and load disturbances. The suggested controller performs powerful functions for improving the adaptability and robustness of hydroturbine generator set. |
