Optimal Design of Concrete Pumping Displacement Control

Abstract:

To solve the problems of concrete piston striking cylinder and pumping insufficiency caused by the mismatch between varying loads and system’s open-loop control property, the optimal model of concrete pumping displacement control was built.To be precise, the displacement control signal parameters were taken as control variables, and the location parameter of the main cylinder’s displacement sensor was taken as structure variable. under the physical constraint condition of non-collision between piston and cylinder, the piston stroke maximizing was taken as objective function and the optimal model of concrete pumping displacement control was built.Optimization result shows that piston of concrete pumping system don’t strike cylinder and pump sufficiently under varying loads.This optimal model, which is built in the integration design space of structure variable and control variables, is of guiding significance for solving open-loop system’s engineering control problems.
