Precise Tension Control of Micro High-Speed Tensioner under Braking Torque Adjustment

In order to achieve precise and rapid tension control of magnetic powder brakes in unmanned aerial vehicle deployment guidance rope systems, the corresponding control algorithm is studied based on its mathematical model. Due to the magnetic hysteresis, the Smith prediction control method is proposed. The Smith prediction control set a high requirement on mathematical model of the system, so the fuzzy control is utilized to form fuzzy Smith control. On the basis of this integral to the output of the fuzzy control to realize the ideal control effect, the computer simulation of conventional PID control and fuzzy integral Smith predictor control is realized by Matlab. The simulation results show that the fuzzy integral Smith predictor control with higher practicability to time delay systems as magnetic particle brake compared with conventional PID control.
