Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adaptation control method for variation of heating value of sludge gas capable of continuing a stable operation by automatically rewriting a control parameter of a control device without relying on experience of an operator, when calorie of the sludge gas is stable in a short time while varying in a long time. SOLUTION: An adaptation rule is provided in which an output difference E(s) between a reference model Hm(s) and an actual plant H(s) is calculated, and fuel flow rate Wf supplied to the actual plant H(s) is adjusted so as to set the output difference E(s) at zero. This adaptation rule considers variation of the plant as 1+Δ times, determines the Δ from E(s)=Δ.H(s), determines a new correction coefficient C(s) from a correction coefficient C(s)=C(s)/(1+Δ/ K), determines a corrected fuel flow rate Wf' by integrating it with the fuel flow rate Wf supplied to a gas turbine plant, and repeats the processes until Δis within an allowable error.
