Design And Realization On The1Meter Scale Wind Tunnel Attack Angle Control System

Aircraft Angle of attack institutions exclusively to test technology in wind tunnel in thepitch in all kinds of vehicle research, lateral spreads Angle the aerodynamic characteristicsof flight, the technology that is the core of attack Angle institutions control system device.With China’s independent research and development of new aerospace products, such as bigplanes, advanced fighter aircraft program.through advanced testing for a domesticmuch-needed1meter scale, caliber Mach number range in0.4to test the wind tunnelbetween three velocities4.0aerodynamic test platform. Unit interior original0.6meterstemporary blunt type half backflow wind tunnel control system function is simple, theoperation inconvenience, reliability is not high, can’t adapt to new space model of the eradevelopment demand, in the task of1meter scale new wind tunnel developed new Angle ofattack institutions control system is imminent.This paper introduces the Angle of attack agency control system test technology indomestic and foreign research and development situation, in detail elaborated thedevelopment1meter scale attack Angle institutions control system, analyzes the importanceand necessity of attack Angle institutions control system, combining the composition andfunction of the development trend of current electromechanical integration, puts forward theac servo control system scheme. This control scheme mainly adopts industrial PC (IPC),MPC2810movement control CARDS, Panasonic MINAS ac servo motor and panasonicMINAS ac servo drive as the core components of the control system. In detail thepermanent magnet ac servo technology, on the basis of its ac servo system dynamicperformance made detailed theoretical analysis, and use of Matlab software in actualsimulation calculation. Using Labwindows/CVI as a platform of industrial control softwaredevelopment and design, realize the real-time network communication and control.According to actual needs, puts forward the experiment based on PCI-1730acquisitioncard consecutively variable Angle of attack for the control schemes, and successfullyapplied to the AGARD-B standard model test, contrast test data completely accords with theGJB1179-91high speed wind tunnel and low speed wind tunnel flow field qualityspecifications ", for the development of our country key model aircraft provide reliablesafety test platform.
