Development And Study Of Software For Flexible-Profiling Automatic Spraying System

"Development of Flexible-Profiling Automatic Spraying System" is one of the National "863"High Technology Program. This paper mainly presents the development of the control software of system,the basic theory and key techniques applied in the system.The "Flexible-Profiling Automatic Spraying System" is the advanced equipment developed for high quality and multi variety automatic production of automobile industry. Flexible-Profiling technology is one of the key technologies. Firstly,the paper introduces the detailed process of the path layout,gives the interpolation arithmetic that is synchronous with the conveyer belt,and describes the realization of the control system. Based on the features of the spraying-cup,such as large lagging,strong coupling,serious nonlinearity the system applies the fuzzy control method. Secondly,the paper introduces the fuzzy control theory and the fuzzy controller design. Furthermore,the diagnose technology is also applied in system. At last,this paper discussed how to solve the problem in the whole procedure of the development.Multifold technologies are applied in the system,such as digital communication,CNC,real-time monitor,fuzzy control,so the system is more accurate,reliable,flexible,and with a degree of intelligence. The system achieves the design request,and satisfactory effect is obtained in actual production.Liuxin(Control theory and control engineering) Directed by Nie erlai...
