摘　　要：本文利用非线性控制的逆系统方法,将大型同步发电机非线性励磁控制问题变换为一个相应的线性最优控制问题,设计出便于实现的非线性励磁控制规律。经仿真研究表明,所设计的控制律显著地改善了电力系统暂态过程的动态响应,较大地提高了静态稳定极限,有效地提高了电力系统的暂态稳定水平。An inverse system method, which was developed to design nonlinear control system, has been used to convert a nonlinear excitation control problem of synchronous generator to a linear optimal control problem. The derivative control law is easy to be realized. The simulation results show that the dynamic responses of the power system to which the generator is connected are obviously improved. The steady state stability and transient stability of the power system are also improved by the control law.
