This paper proposes the cooperative control of AVR and GOV taking the uncertainty of a state variable into consideration to improve transient stability of power systems. The control laws based on sliding mode control are very simple, and are introduced to take the uncertainty of the state variable into consideration without the linear-approximation of power systems. So, the proposed control has the robustness regarding parameter error and load variation. The state variables which need to control the power system are speed deviation and input/output power of generator only. Therefore, the proposed control can realize in real system easily. The validity and usefulness of the proposed control are tested on a single-machine infinite bus system. It is shown that the transient stability of power system is improved by cooperative of AVR and GOV control sufficiently.
