考虑输出约束的发电机励磁系统非线性控制

摘要

For the transient stability problems on synchronous generator excitation system with output constraints, a nonlinear controller was designed based on backstepping method, which not only preserves the nonlinearities of the origin system, but also effectively resolves the output constraint problem of the excitation system by barrier Lyapunov function. The results of simulation show the effectiveness of the proposed method.%　　针对发电机励磁系统在输出约束条件下的暂态稳定性问题，应用backstepping方法设计了非线性控制器。该控制器不仅保留了原系统的非线性特性，而且利用约束 Lyapunov 函数有效地解决了励磁系统中输出量限幅的问题。仿真结果表明了设计方法的有效性。
