A winch control system consisting of a drum loading system,electro-hydraulic proportional braking,and driving system was designed to address the issues of poor stability and low coordination in the winch control system,which relies on manual operation.When there is no auxiliary braking system,the speed fluctuation time during the starting phase is 4 s,and the fluctuation amplitude is large.When there is an auxiliary braking system,the speed adjustment time is shortened to 3 s,the fluctuation amplitude is small,the speed tracking performance is good,and the coordination and cooperation between the drive and braking systems are good.The entire operation phase is stable and without any sudden changes,which improves the reliability of winch operation.
