The invention relates to a micro fuel gas turbine technology, whose structure includes turbine burning controller and control method. The controller includes PUT, detecting unit, output unit, photo-electricity coupling unit, and driving unit. The control method is realized by computer program module that includes system initialization, self-testing, burner firing, power closed loop adjusting block, stop and turbine capability index real time monitoring module. It adopts neural network PID controller adjusting method. It improves control accuracy, decreases technology cost and increases the stability and safety of the system.
