Design of a Follow-up Throttle Based on PID Control
Aiming at the automatic development of the aircraft,a throttle control system with follow-up function is de-signed.The system uses STM32F103 microcontroller as the main control chip,and realizes the data interaction by us-ing the sending and receiving function of USART module inside the chip.The system feeds back the position informa-tion of the throttle stick in real time through the position sensor,and transmits the feedback information to the control station.At the same time,the throttle receives the follow-up command from the control station,and drives the stepper motor through the PWM function of the microcomputer to realize the follow-up control of the throttle stick.Finally,the upper computer testing system is written to execute tests,store and process test data,and complete the joint de-bugging test of the throttle control system.The results shows that the design scheme of the servo throttle based on PID control algorithm is feasible.
