Description

technical field [0001] The invention relates to a control device, in particular to a digital control device for a micro gas turbine. Background technique [0002] Most of the existing micro gas turbine controllers use a mechanical fuel regulator or an analog circuit controller to adjust the fuel and then control the micro gas turbine speed and exhaust temperature after the turbine. Mechanical fuel regulators have high requirements on shape and position tolerances and material properties, and their structures are complex. The analog circuit controller has large temperature drift and poor environmental adaptability. At the same time, the two are generally only suitable for micro gas turbines with specific performance. After the control law changes, it is difficult to adjust: the mechanical fuel regulator often needs to redesign the structural size of the internal components, and the processing cycle is long and the cost is high. The analog circuit controller needs to replace...
