Abstract
Toward the development of 5kW micro gas turbine (MGT) fueled by biomass gas, we developed the software for controlling supply fuel gas. The rotational speed of the output shaft of the power turbine is controlled to maintain the target speed. Two fuel flows for the primary combustion zone and secondary combustion zone in the multistage combustor are controlled. The role of fuel flow control for the primary combustion zone is to adjust flow of city gas 13A to stabilize the tubular flame. The other fuel controller adjusts the flow of mock biomass gas to the secondary combustion zone to maintain turbine speed for various load and fuel components. As for the control scheme, two controllers based on the modern control theory (H infinity theory) and classical control theory (two DOF PID theory) for multistage combustor were tested and successful operation was achieved.
