Research On The Lateral Track Correction Strategy For A Class Of UAV

As information technology is widely used in the military field, and more remotely modern warfare combat and air raids as the main means of attack, air and missile defense and therefore face more severe challenges, and to intercept air threats target air defense weapon system test is the test and evaluation process in an important pilot project, a variety of air defense weapons testing, evaluation, and military training, the urgent need to be realistic simulation of air threats target simulation systems, and a class of unmanned aerial vehicle is the test and evaluation of air defense weapon system air and missile defense battle the ability of the most real and effective, the most convincing high-level simulation system. Therefore, these aircraft and flight application technology research and development, have become an urgent need to develop special areas.With the rapid development of the national economy, flight zone is narrow, multi-platform, multi-objective test against zero shortcuts against other test conditions need to simulate the system with higher precision tracking control and safety. The existing class of unmanned aircraft in the flight path control accuracy cannot meet the demand for analog adversarial trial system. To improve the accuracy of such aircraft lateral track control, expand the topics for unmanned aircraft lateral track correction strategy research to a class of aircraft as the research object, through the analog channel system autopilot heading control strategy analysis, made by introducing a lateral track position information for correction methods. The main work is given as follows:First of all, on a class of unmanned aerial vehicles and lateral track correction research status and development trend of technology are reviewed, the development and the application of navigation technology are introduced, and the overall needs analysis.Secondly, the introduction of the aircraft by reference coordinate system to study the aircraft dynamics, kinematics and control system model, and the existing analog system autopilot heading control theory and comparative analysis of the test results.Then, according to the general requirements of aircraft lateral track control accuracy, the design of lateral track amendments to the program, selected on the principles of navigation were introduced, the control system is switched problem and location information hopping problem, gives a solution, and were simulated and compared.Subsequently, for the realization of digital PID control is designed to control devices. Describes the functions and composition of the control device, respectively, of the control device hardware design, component selection and design software main program. Finally, a test environment, the use of Lab Windows/CVI software for semi-physical simulation test system has been implemented in software, and the simulation test, simulation results show that:the introduction of location information for lateral track correction method is effective.Finally, the work done in this paper are summarized, and pointed out the direction for further study.
