Abstract :
This paper is devoted to synthesize the problem of transient stability and voltage regulation in power system with bounded uncertainties. The proposed control scheme is obtained as a robust controller in terms of linear matrix inequalities (LMIs). This paper adopts the direct feedback linearization (DFL) technique to establish a linearized model, where both phase and voltage are considered in the feedback states. The simulation work is given to demonstrate that the proposed robust control scheme is effective in achieving transient stability and voltage regulation concurrently.
