For this problem, by increasing the automatic flat system of loader attachments that achieve flat of bucket in raises simplifies the process in a way and reduces the operator intensity of working in this paper.

Modeling Design of Automatic Lay-out System for Supermarket Based on UML;

According to the structure and principle of roughness measuring instrument, the measurementcourse of the roughness is simulated using MATLAB,the quantitative relation between roughness index and pavement state parameters are analyzed, and the actual meaning and feasibility to establish new controlling methods of auto-leveling system for paver and improving the pavement roughness are expounded.

This paper approaches automatic control system for elevation of DEMAG DF-140CS pitch paver, summarizes the faults in use for the purpose of any help to the practice of operation.

Based on the engineering cybernetics and optimization theory, this paper puts forward the parameters optimization method which takes slope response ITAE criterion as a target function in order to let the automatic control system for elevation has a optimal following performance.
