Abstract—A new design method of non-linear control system is provided in this passage. Exact Feedback Linearization theory of differential geometry is applied to the design of non-linear excitation control law for the single-machine infinite system, and non-linear excitation control law of generator is obtained, the design method provided in this message is very simple, Matlab/Simulink remains that excitation controller based on non-linear theory is very effective for the improvement of system stability and the stability of generator terminal voltage compared with the LOEC and traditional PID controller.

Keywords—generator, excitation control, non-linear coordinated control, differential geometry
