Design of a H/sub /spl infin//-optimal servo compensator for the frequency and voltage control of power plants

This paper investigates modern H/sub /spl infin// control concepts for frequency and voltage control of power plants. Based on a linearized model for a national grid H/sub /spl infin//-optimal servo compensators have been designed using a frequency domain approach recently published by the authors (1993). As demonstrated in this paper, the multivariable H/sub /spl infin// controller shows superior performance with respect to settling time and damping of oscillations compared to classical controllers of P/PID type.<<ETX>>
