Robust controller depends on H infinity optical control theory was designed and developed for a new Micro Gas Turbine capable of biomass gas. It was required for the system to be stable for unpredictable fuel components fluctuation while maintaining the control performance. The H infinity controller was designed based on the system identification and the weight functions determination. After confirming the stability of both the controller and the system by the simulation, it was equipped to the Micro Gas Turbine experiment system. It showed not only similar control performance than conventional 2 Degrees of Freedom PID controller, but also significantly higher robustness after the resolution of fuel flow controller was changed. This development made the Micro Gas Turbine stable against finer fuel control, and this realizes higher controllability under fluctuating low calorific gas fuel such as biomass gas.
