Control Characteristics Of Traction System Of Electric Optic/Electric Composite Cable Winch

In order to meet the deep sea development of China’s marine resources and environment survey.Optic/electric composite cable winch as a hydraulic device for deep sea probe can ensure the safe and effective operation of underwater equipment.Because the domestic deep sea winch is in the initial stages of development,it mainly depends on imports.The task of deep sea winch domestic development is urgent.Optic/electric composite cable winch have functions of retractable and communicated.Its performance directly determine the quality and safety of underwater equipment.According to the performance of composite cables and characteristics of large capacity control,the structure form of traction winch and cable storage separation is selected.The research mainly on control characteristics of traction system about optic/electric composite cable winch,including mechanical analysis of traction systems,model and simulate of speed control system and control research of PLC platform.First of all,for traction systems of optic/electric composite cable winch lack of theoretical basis is a key issues of composite cable and drum designing.Optic/electric composite cable force analysis in dual drum was carried out using calculus and Matlab simulation method.The mechanical model of composite cables on drums were obtained.In turn,the tension changes of composite cable on traction drums were discussed.Simulation results of ANSYS software for finite element analysis to verify that the established mechanical model of the traction cable.Secondly,with electric traction control system as the core,the servo control system model of was established.It based on analysis of three-phase asynchronous motor vector control.By the simulation of Matlab/Simulink,the control characteristics about PID control and the optimization of fuzzy PID control of traction winch system was researched respectively.Simulation of fuzzy PID control can better overcome disturbances,reduce the overshoot and to improve control precision than PID control.Finally,based on the features of the traction winch control system and simulation of PID results,the traction winch control system was established.The system used PLC and transducer control module.Software of double drum master-slave control was compiled,and relevant human-machine interface was designed.
