| Abstract: | Aimming at the fuel control requirement of micro-turbojet,the automobile's electric fuel pump with adaptable improvement is chosen as fuel-feed system.The performance of fuel pump and the technical difficulty of flux control as the speed of pump doesn't be measured are analyzed.Using Philips 83C552 MCU as the main control chip,the system adopts voltage negative feedback combined current compensation instead of rotation speed negative feedback and a PWM convertor to design the flux closed loop control system.Base on system simulation,PID controller design and simulation,the system of experimentation is constructed and tested.The test result shows that the designed fuel-feed system can satisfy micro-turbojet fuel supply requirement. |
