| Abstract: |
| With the coupling among three-axis platform frames of tracking and sighting pod taken into consideration, the kinetic equations are set up according to the kinetic characteristic. Moreover, by predigesting the equations, the math model suitable for controller design is gained. An H-infinity controller combining with Kalman filter is designed for stabilizing loop of tracking and sighting pod platform frames. Fuzzy PID controllers corresponding to each tracking loop of three-axis frames are designed. The control system designed in this study, in which the effects of the coupling among frames and parameters variation are taken into consideration, is closer to practical situation. The control system is dynamically simulated under the condition of multidisturbance. The simulation results show that the entire stabilization tracking control system has good robustness and high tracking precision, which fulfils the need of stabilizing and tracking control of tracking and sighting pod. |
