摘要
根据激光半主动制导武器的特点建立了该类武器制导与控制系统半实物仿真模型。通过分析误差对半实物仿真的影响,指出几何误差的影响较大,并建立了误差数学模型。通过数学仿真,在脱靶量的允许范围内给出了最大允许角误差。为消除误差,设计了导引头闭环跟踪半实物仿真实验。利用仿真结果建立了误差参数超定非线性方程组,并使用牛顿迭代法和加权最小二乘法的组合算法来解算。此项研究工作有效地提高了仿真精度,同时也提高了基于该类平台半实物仿真实验的置信度。
According to the characteristic of laser guided weapon, a hardware-in-the-loop simulation （HILS） model for guidance and control system was founded. Then, all kinds of errors impacting on simulation system, especially geometric error, were analyzed, and a guidance model with error was created. Through the mathematic simulation, the maximal angle error was given to limit miss distance within allowable range. In order to correct the geometric error, a model of HILS was developed for seeker to track a certain laser spot on curtain. Using the obtained results, nonlinear over determined equations of error parameters were established. With combination of Newton iteration method and weighted least square method, the error parameters were solved and geometric model was corrected accurately. The results indicate that this approach has achieved exceptional accuracy and reliability, which is significant for next phase of HILS.
