Abstract :
This paper investigates modern H∞ control concepts for frequency and voltage control of power plants. Based on a linearized model for a national grid H∞-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∞ controller shows superior performance with respect to settling time and damping of oscillations compared to classical controllers of P/PID type
