The Immersion and Invariance(I&I) methodology provides a novel approach for nonlinear system control, which is distinct from the traditional feedback linearization and backstepping method.In this paper,a new excitation controller is designed for single machine infinite bus system(SMIBS) based on the I&I approach.Firstly the dynamic model of SMIBS is homeomorphously transformed to a specific form for which a stable lower-order target system is selected.Then the I&I excitation controller is designed by immersing the transformed system into the target system.Simulation results from PSCAD/EMTDC demonstrate that the proposed controller guarantees transient stability of the system after large disturbances.
