Nonlinear stabilizing control of multimachine systems

A novel approach is presented to nonlinear control design for multimachine systems using differential geometric theory. A mathematical model in the form of an affine nonlinear system is set up for the design of a large-scale power system. As an example, the approach is applied to nonlinear steam-valving control. The control law obtained is implemented by purely local feedback. The stability of a global multimachine system with the nonlinear control is illustrated by the results of simulation on a six-machine system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
