This paper presents a nonlinear variable structure excitation controller, which combines the advantages of nonlinear differential geometry and variable structure control theory. The simulation analysis of decentralized control for static and transient stability of classic multi-machine system is compared with that of nonlinear optimal excitation control. The simulation results show that the nonlinear variable structure control gives more satisfactory dynamic response characteristics and better robustness.
