Human-in-the-loop Design And Performance Analysis Based On Hardware-in-the-loop Simulation

Hardware-in-the-loop(HILS)simulation test is an indispensable link in the design of guided bomb.It is more effective and reliable than the mathematical simulation test,meanwhile it can greatly reduce the number of field shots and reduce the cost.The two situations are as follows in the actual combat process of the image-based navigation bomb hitting the ground target: The battlefield interference and target camouflage can cause the seeker to fail to capture the target,which in turn make the bomb unable to eliminate the navigation system measurement error and result in decreasing the accuracy;In addition,when the pilot identifies that the target to be hit is a fake target or a low-value target through the seeker,or he finds that the original target has been destroyed,then he needs to change the target to be hit.Aiming at above two actual situations,a guided bomb's HILS system test scheme of human-in-the-loop is designed.The main research contents are as follows:Firstly,the contents of the design and mathematical simulation verification part of the guided bomb guidance control system in other people's papers are cited.Then the paper introduces the design of the HILS system in the laboratory.And a general scheme of human-in-the-loop HILS system is proposed based on the research content of this paper.Secondly,this paper explains in detail how the navigation system measurement error and the target temporary change decrease the accuracy of the guided bomb based on the background of the image-based navigation guided bomb hitting the ground target.In view of these two situations,the design of the human-in-the-loop guidance control scheme is proposed,and the system design of the human-in-the-loop HILS is also given.Finally,in this paper,the test scheme is designed and the test system is built,and the human-in-the-loop HILS test is carried out.The human-in-the-loop program and human operation level are also established to evaluate the performance of different schemes.The performance of the human-in-the-loop scheme is verified through the comparison and analysis of the test results.
