摘要：

为了解决励磁系统的不确定性影响互联电力系统的稳定控制问题,提出一种新型的鲁棒自适应控制器递推设计方法.与传统的Backstepping设计方法相比,新方法减少了对被控对象的严格要求,所设计的控制器避免了过度参数化和复杂化问题,能够保证闭环系统对不确定参数的自适应性以及对建模误差和有界外部干扰的鲁棒性.采用该方法设计的电力系统新型励磁控制器在华东电网上进行数值仿真,结果表明,所设计的控制器能够有效提高互联系统的暂态稳定性.
Abstract:

A new recursive method was proposed for nonlinear robust adaptive controller design in order to solve the stability control problem caused by the uncertainty of the excitation controller model. Compared with the conventional Backstepping method, the method reduced the requirements to the controlled system, and avoided over-parameterization and complexity problem while it can also guarantee the system adaptive to uncertain parameters as well as robust to model errors and bounded external disturbances. A robust adaptive excitation controller was designed based on the method, and numerical simulation was conducted on the East-China Power Grid using the controller. Results demonstrate that the controller can effectively improve the transient stability of interconnected electric power system.
