Fuzzy self-adaptive PID control in actuator control system of unmanned aerial vehicle

According to response speed slow, over regulation measurement great, transient time long and anti-interference ability low, actuator control system of unmanned aerial vehicle based on fuzzy self-adaptive PID control was designed. The three parameters of PID controller were adjusted adaptively on line by fuzzy self-adaptive PID control, which was designed by self-adaptive principle, fuzzy theory and traditional PID algorithm. Simulation result showed that after the parameters self-adaptive Fuzzy-PID controller being used, control system response speed quicken, over regulation measurement greatly reduced, transient time shorten, fluctuation times decrease and pressure governing precision advanced.
