Abstract: According to the control　demand　of　a　certain　small　turbojet　engine,the　project　of　a　digital　electronic　control　system　was　constituted,the　control　law　of　engine　starting,accelerating,decelerating　and　steady　state　control　was　designed.A　digital　electronic　controller　was　manufactured,the　control　software　design　was　accomplished,and　the　control　system　hardware-in-the-loop　simulation　test　was　carried　through.The　test　result　indicates　that　the　performance　of　the　digital　electronic　control　system　designed　in　this　paper　is　preferable,the　control　demand　of　a　certain　small　turbojet　engine　is　matched.
