| 摘 要： | 针对汽轮发电机组主汽门控制系统在状态约束条件下的暂态稳定性问题,应用backstepping方法设计了非线性汽门控制器。该控制器在未对原系统进行线性化的基础上,利用考虑约束的Lyapunov函数,解决了汽轮发电机组主汽门控制的状态量幅值约束问题。仿真结果验证了设计方法的有效性。

| Abstract: | In view of the transient stability of the steam turbine generator unit with main steam valve control and multiple state constraints, an adaptive nonlinear controller was designed by using backstepping method, which not only preserves the nonlinearities of the origin system, the problem on multiple state constraints is also effectively solved by barrier Lyapunov function. The simulation results show the effectiveness of the design method. |
