Design of Double Cranes Synchronous Control System Based on ControlNetwork

摘要

To solve the problems in the synchronous operation control of double cranes for lifting super long rail, fuzzyparameter self-tuning PID was introduced to the synchronous operation control strategy of the non rigid connection mechanism.For practical application in concrete engineering project, a fuzzy PID double crane synchronous operation controlsystem was designed, which was implemented by PLC in control network. The network topology structure and systemsoftware and hardware configuration were introduced in detail. Structure of the fuzzy PID controller and its specific implementationprocess in Siemens CPU315-2DP PLC were explained also. Meanwhile, software aided design and simulationexperiments for the fuzzy PID controller by making use of the simulation software MATLAB were explained. Theresults of simulation and practical operation effect show that, some control quality indexes of the fuzzy PID controller likeovershoot, dynamic response speed and steady-state accuracy are greatly improved compared to the conventional PID.Because of the design based on control network, the system operation efficiency, real-time performance and economicbenefit are also improved considerably, so it has the high value of engineering application.
