Abstract


Has a unique ability to fly unmanned helicopter , the military and civilian aspects of the growing demand for unmanned helicopter flight control technology has broad application prospects and extremely important practical significance . Unmanned helicopter flight control system software is an important part of the UAV flight control system , is increasingly important in the design of the flight control system , and its performance is directly related to the success or failure of the flight . Based on the embedded real-time operating system μC/OS- Ⅱ, constructed μC/OS- Ⅱ core unmanned helicopter flight control software design of the new development system. Design embedded and desktop two flight control software , and services for the different stages of the development of flight control . Meanwhile , the two sets of software interrelated and complement each other , the only difference between them is that the part of the underlying driver , the control law is part of the code can be 100 % of the transplant . First , on the basis of the current results , embedded onboard software μC/OS- Ⅱ transplantation , including the contents of the development environment transplantation , transplantation of the CPU , the global variable security reader , Fixed-Point Algorithm , etc. . Secondly , in the full grasp the interruption management mechanism on the basis of μC/OS- Ⅱ designed serial communication module interrupt μC/OS- Ⅱ (OSCom module ) , not only to achieve independent interrupt of the serial port , and to achieve a string line ports share interrupt . Finally, according to the the equivalent flight control \Two typical configuration , the the equivalent flight control technology . All all of Experimental verification of the physical environment , the results show that the design project is feasible .
