英文摘要： Hardware-in-the-loop simulation has played an important role in evaluating precision-guided weapons. For simulation equipment, deviations of dynamic parameter such as innate amplitude or phase, and error factors such as assembly errors or metrical errors, are closely related to working mechanism and performance of simulation objects. This will directly affect hardware-in-the-loop simulation experimental precision, reduce simulation credibility and expand the differences between ground experiment and in-flight experiment. Considering hardware-in-the-loop simulation of precision-guided weapons, error propagation mechanism is researched for various types of simulation equipment in closely coupled and nonlinear systems. Using theoretical analysis and experimental verification construct model of multiple and different types of simulation errors which is based on facility index. In this study, we will analyze coupling principle between simulation equipment and objects to construct model of guidance and control closed loop with simulation equipment errors. This study put forward multi-index weighted fusion algorithm of evaluation criterion on simulation precision. Using SLAM studies simulation equipment errors propagation mechanism in closed coupling and nonlinear systems. We will quantify simulation equipment errors` influence level and define the errors` effect tendency on simulation precision. We will allocate equipment index which is under multi-constrained conditions, such as costs and precision, based on mapping relation simulation experimental precision and equipment index. The achievement of this research will provide theoretical basis and technical support to improve Hardware-in-the-loop simulation experimental precision and reliability of precision-guided weapons.
