Nonlinear L2 Design for the Generator Hamiltonian System Included Excitation and PSS

In this paper, the generator included typical automatic voltage regulation (AVR) and power system stabilizer (PSS) SCR excitation system is taken as the research object, The Hamiltonian energy function and its general Hamilton control model are analyzed, on the basis of the five order Hamilton system model, positive definite conditions of the damping matrix R(x) was derived, and the system dissipation characteristics was analyzed. Using the Hamilton energy design method, the control strategy of system was designed, under the above control, the system is finite-gain L2 stable when external disturbance occurs.
