利用暂态能量函数法研究双轴励磁同步发电机的非线性最优励磁控制。考虑系统的非线性特性推导出非线性最优励磁控制规律，并与单励机及双励机的线性最优励磁控制进行了比较。仿真结果表明，本控制方案有效地改善了电力系统运行的静态及暂态稳定性。
Study on Nonlinear Optimal Excitation Control of Biaxial Excitation Synchronous Generator by Transient Energy Function. Considering the nonlinear characteristic of the system, the law of nonlinear optimal excitation control was deduced and compared with the linear optimal excitation control of single-excitation and double-excitation. Simulation results show that the proposed control scheme can effectively improve the static and transient stability of power system.
