| Popis: | In order to research the influence of different disturbance rejection rate (DRR) model, the model with different signal point and under a damping moment and spring torque are derived respectively. According to the models the characteristic of seeker and DRR are analyzed. And the relation of DRE and seeker dynamic is proposed. Then according to the different DRR model, the seeker tracking model with DRR is made up and analyzed. To research the influence on guidance loop, the parasitic loop with different DRR models is proposed and analyzed in frequency region, which can provide a reference unstable frequency for control system. Furthermore, a guidance loop with different parasitic loop of DRR is established, and the analysis shown that, the signal outputting point is an significant factor for miss distance in different disturbance torque. At last, a test method based on the guidance and control system is proposed which can show the characteristic of seeker model with parasitic loop effetely. |
