Continuous Control Design for Synchronous Machines

For transient stability of a synchromous machine connected to an infinite bus, a new controller is introduced. The control is continuous, guarantees global exponential stability, and robust with respect to possible variations of system parameters. The design procedure is based on a straightforward application of Lyapunov´s direct method. Neither local linearization nor feedback linearization is required. The design procedure as well as the resulting controller can be easily extended to a multimachine power system. Digital simulation is included to demonstrate the effectiveness of the control.
