摘要： This invention relates to a method of performing control of a closed loop control system controlled by a controller, wherein said controller delivers the control input to at least one control unit in said system e.g. a valve, said method comprises the steps of: - detecting the oscillation level in said control input to said control unit, - amplifying said control input by a multiplication factor based on said detected oscillation level. Thereby characteristics of the control unit are changed as oscillations are detected. Thereby oscillations are minimized, and e.g. the wear of the control units is reduced and an improved control is obtained.
