Starting Process Control of Small Turbojet Engine Based on Rapid Control Prototype Technology

In order to quickly verify the control law of small turbojet engine starting process,a semi-physical test platform is built based on rapid prototype technology.The overall architecture of the rapid prototype test system is designed.The software and hardware design of the control system and the working principle of the smart node are described.The Speedgoat Mobile real-time target machine is used as the electronic controller,and the STM32 is used as the core to design the smart node.Modbus protocol is selected to encode the signal to realize the data communication between the electronic controller and the smart node.A control law is designed for the starting process of a small turbojet engine.The executable program of the electronic controller is generated by using the automatic code generation technology and deployed to the real-time target machine to run.The experimental verification of the control law of the starting process is completed.The simulation results show that the electronic controller and smart node work reliably and stably,and the starting process is stable and rapid,without stalling,overtemperature,and overrunning.The rapid control prototype technology can effectively shorten the development cycle,and has good engineering practical value.
