| 摘 要： | 针对捷联惯性/合成孔径雷达组合导航系统中SAR测量信息的分段性和时滞性问题,利用一类混杂时滞系统模型对该组合导航系统进行建模,提出一种切换伦博格观测器,用于估计组合导航系统的状态,进而实现组合导航。给出了切换伦博格观测器的设计方法,并从理论上分析了该观测器的解析性能;证明了该观测器的状态估计误差是收敛的,且收敛性与系统工作模式切换的顺序和测量信息的时滞性无关。最后通过仿真试验验证了所提方法的可行性和有效性。

| Abstract: | The SAR measurements have unequal interval and time delay in SINS/SAR integrated navigation system.In such case,the SINS/SAR integrated navigation system is modeled by a hybrid time-delay system model,and a switched Luenberger observer is proposed to estimate the states of the system model in order to correct the position and velocity errors.The switched Luenberger observer is deduced and the performance is rigorously analyzed.Simulation results demonstrate the feasibility and effectiveness of the proposed ... |
