Abstract :
This paper presents a multivariable controller design based on the linear quadratic Gaussian with loop transfer recovery theory to control power generation, excitation machine and power flux between generator and grid for an induction generator system operating at variable speed. A disturbance speed rotor change was simulated and results show the ability of the proposed controller to regulate slip machine, rotor flux, DC link voltage and reactive power delivered to grid
