摘要

This engine control device comprises the following: a control unit which controls an object to be controlled and which contains an engine;a vibration extraction unit which extracts one or more vibration components superimposed by the response of a control system based on one or more resonance characteristics of the object to be controlled;a follow-up frequency estimation unit that sequentially estimates the frequency of a vibration component under the vibration components and emits the estimated frequency as a vibration frequency estimation series;and an estimate unit for a number of resonances,which, on the basis of the vibration frequency estimation series, produce the number of resonance characteristics that cause the vibration that is superimposed by the response of the control system, when the range of estimates of a number of resonances is emitted and Kerbfilter is installed in a number according to the value of the range of estimates of a number of resonances,and the output of the control unit is given to the power control unit by means of a notch filter to control the engine.
