Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adaptation control method for variation of heating value of sludge gas capable of preventing misfire or excessive temperature in the inverse case that cannot keep combustion 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 but varies in a long time. SOLUTION: In an idle rated rotation after reaching idling, an output difference E(s) between a reference model Hm(s) and an actual plant H(s) is calculated, correction coefficient C(s) for setting the output difference E(s) at zero is determined, and, after turning on the system, application of an adaptation rule is stopped, the determined correction coefficient C(s) is stored in a memory and is used as an initial value in a next starting time.
