Design Of Aircraft Canopy Test Bed Control System Based On LabVIEW

In the development of modern high performance and high maneuverability aircraft,it plays an important role in the strength fatigue test of all parts of the aircraft.The warming & loading test bed for the cabin cover is a ground test bed for the safety test of the cabin cover in the cockpit,which can verify the load test capacity of the specific model of the cabin cover in the early design stage,and reduce the potential safety hazard of the plane under the real flight mission conditions.This paper first introduces the design principle of the heating & loading test bed of the cabin cover,calculates and analyzes the heating power and cooling capacity of the system,and verifies the test capacity of the system.The composition and corresponding functions of each subsystem of the test bed are introduced.Then through the modeling analysis of the system,the expression of the pressure system transfer function is obtained according to the state space equation of the pressure system.Aiming at the temperature overshoot and temperature lag caused by the large surface heating area and the long heating pipe during the cabin cover heating control test,a temperature adaptive fuzzy PID controller was designed,and the system model was built under the MATLAB/Simulink module and the simulation control test was carried out.Lab VIEW provides a graphical programming method with higher programming efficiency.It USES high-performance modular hardware to complete various tests.With the help of Lab VIEW development platform,it designs a set of program software for the cabin cover heating and loading test bed.Through the selection of equipment and the design of software system,the remote test control of the cabin cover heating loading test bed is finally realized,and the field mission load test is carried out on the test bedThe test results show that the system controller designed in this paper can meet the technical requirements of the test bed of cabin cover heating and loading,verify the correctness of the system design,and provide a basis for the control design of the test bed in the future.
