Rapid Prototype Design For Flight Control Software Of UAV Based On XPC Target

As great benefits are got from the applications of UAV (unmanned aerial vehicle),especially the applications in military, more and more attentions are paid to the development of UAV in the world.In this paper,the design and realization technology suitable for rapid prototyping design of UAV Flight Control System are presented.The practice and application is emphasized.That rapid prototyping design using Host-Target mode of xPC Target is based on traditional UAV Flight Control System.The whole platform of rapid prototyping design include Host PC,Target PC and miniature simulation equipment.Host PC is used in developing;Target PC is a flight control computer which is running execution code;Miniature simulation equipment is the peripheral equipment of the Host-Target mode which is running UAV model.According to driving designing of xPC Target, this paper designs software driving of the non standard plate card of NUAACOM8.That sloves the problem of serial port communication.According to xPC Target user interactive interfacial technology, this paper realizes controlling target, display of sensors singal, the output of actuator, remote control and adjustment,adjusting parameters on-line,display of flight path and display of historical curves.According to the code of the flight control,this paper modulars and integrates the code of flight control in the simulink.This paper modulars sensors,actuator, remote control and adjustment,control logic of automatic navigation and control law.That provides experimental object for the way of rapid prototyping design of Flight Control System with xPC Target.Finally,we carry out the way of rapid prototyping design of Flight Control System with xPC Target of half physical simulation experiment.The result shows that the design is conscientiously feasible in project.
