针对舰船电力系统中存在的非线性、不确定性和发电机之间相互影响等因素,应用直接反馈线性化技术与增益调度多目标理论设计发电机励磁控制,以阻尼电力系统小信号振荡,提高瞬态稳定性.仿真表明,系统负载功率突然改变时,该控制方法能有效改善系统瞬态稳定性.
The direct feedback linearization (DFL) technique to- gether with the gain scheduling multi-objective control theory are further developed and applied to design nonlinear excitation com- pensators, which selectively eliminates system nonlinearities and deal with plant uncertainties and interconneetions between gener- ators. Digital simulations show that control scheme achieves uni- fied transient stability in the presence of parametric uncertainties and significantly sudden changes in the network parameters.
