| Summary: | Delay of the control system may introduce large error of non-linear position precision during the rising process of a JJC catenary working platform. It built a mathematical model for the platform lifting mechanism and analyzed its movement characteristics. By taking fixed out quantity of the drive cylinder as the research object, the problems that the environmental temperature and program update factors that influence the control precision have been solved using self-learning method. The experimental results show that the error can be reduced from more than 10 mm to less than 3 mm between actually stop height and original set height, which successfully meets the technical requirements of 10 mm design precision between the two platforms. |
