A Research Of Laser Processing System Based On PC104and FPGA

In modern industry, multi-motor synchronization controlis a commonproblem.The precision of Multi-axis synchronization often directly affect theproduction quality ofproducts. Therefore, the research is of great significance.This paper is based on the national major equipment special project-research anddevelopment of femtosecond laser equipment used for developing the performance ofnew type of aero-engine. We analyze the principle of wedge block scan processingsystem, make the construction of the double synchronous motor drive high speedrotation wedge block structure,to control the laser beam scanning trace.We completethe design of hardware and software and control method of permanent magnetsynchronous motor research,whichpoints out the direction for further improve thesynchronization performance.In this system,the control card made by ourselves choose PC104microprocessorsand programmable logic devices produced by ALTERA company as the maindeviceand choose Japan panasonic A5actuator series ac servo motor and drive.Byrotating electric engine with high speed,the wedge block is drove to rotate.We usetheincremental photoelectric encoder as speed and position feedback and the finalassessment reference signal.For this reason,this paper introduces the key technologiesof movement control cards, the design of the process and the hardware principlediagram.In addition, this article carried on the detailed introduction ofhow to reviewthe system synchronization performance has carried on, and constructed based onLABVIEW and NI acquisition card synchronization precision of the evaluationsystem.After a series of debugging, by using the incremental PID algorithm designspeed compensator, it finally reached a speed of2400r/min in synchronizationprecision of the synchronization under0.3°, and basically meet the need of thesystem, which can satisfy the demand of the actual working condition.
