Design of Parameter of LOS-rate Estimation Based on Hardware-in-the-loop Simulation

Aiming at the disturbance rejection rate problem caused by the incomplete decoupling of LOS-rate estimation in strapdown guidance, the design is proposed. Firstly, a practical LOS-rate estimation algorithm is proposed. Then the time synchronization algorithm of the guidance component and the delay compensation parameter design method based on hardware-in-the-loop simulation are proposed to optimize the LOS-rate estimation algorithm. Finally, the effectiveness of the algorithm and the delay compensation parameter design method is verified by hardware-in-the-loop simulation. The simulation results show that the decoupling effect of the proposed method is good and the disturbance rejection rate problem of LOS-rate estimation for strapdown guidance can be effectively restrained.
