Abstract
A mathematical model of the throttle opening control system is proposed based on the automatic control of the throttle opening of a certain type of UAV (Unmanned Aerial Vehicle) rotor engine in this paper. With this, the simulation model is established in Matlab/Simulink. Furthermore, the simulation analysis of control effect is performed through two control methods: traditional PID control and fuzzy adaptive PID control. Simulation result shows that the fuzzy adaptive PID responses faster with less overshoot than the traditional PID control.
