Title The Design and Development of Control
System for Micro-turbojet
Abstract
The micro-turbojet engine control system is a typical complex system. This article is，from the perspective of engineering applications，to carry out the hardware and software design of micro-turbojet engine testing and feedback control system. This system is designed based on the MEGA16 as the control core, which is used to deal with the temperature and the speed of revolution. After the analysis of the testing in the temperature，the speed of revolution，the data display module and the single-chip feedback control module，combined with the features of micro-turbojet engine control，we give the full performance of the MEGA16 microcontroller. In the practice，we make the focus on the analog signal acquisition，real-time display，and the design of the feedback control system. Through the graduation project，the design of the control system we completed has the advantages as follows： it has simple hardware circuits，full software functions，high speed，high precision，and control system is reliable and cost performance，which can be used for the simple control of the micro-turbojet.
