Design of Dynamic Loading Winch Control System and Tension Control Algorithm

In order to simulate the tension on the cable during the recovery and release process of towing winch, and provide a realistic simulated load for the towing winch. Based on the actual tension changes on the cable during the operation of the towing winch, the control system of the tension winch is designed, and the mathematical model of the speed control system is built based on balance equation, and the fuzzy PID control algorithm is applied to the tension control system, the tension changes on the cable is studied under constant tension control and variable tension control. The experimental results show that the algorithm has a fast dynamic response speed, the cable tension control error margin attains the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\pm \mathbf{0.1}$</tex>.
