摘要
A nonlinear multi-machine power system with steam valving is considered. Through the Hamiltonian structure of the control system a decentralized steam valving control scheme is proposed. It is easy to see that the scheme is linear which is different from the usual linear controller design using the linear approximate model around the working point, and furthermore is simpler than the other design method such as differential geometry. The property of attenuating disturbances is studied in the sense of power angle for the control scheme.
