In this paper, a finite time convergent guidance law is designed considering the missile flight control system (FCS) dynamic response characteristic. The mathematical model of relative motion is built and the FCS is considered as a first-order system. And then, the modeling error and target maneuvering acceleration are regarded as disturbance, which can be estimated and compensated by introducing the extended state observer (ESO). The robustness of the guidance system against the maneuver target can be improved by using back-stepping method and integrating the FCS. The proposed law can guarantee the line of sight (LOS) rate converges to a small bounded neighborhood of zero in finite time. Numerical simulation was carried out, and the feasibility and superiority of the proposed guidance law were verified.

A coarse-fine compound axis cooperative control strategy is presented for the laser tracking and aiming system according to high precision, fast response and anti-jamming requirements. The coarse tracking infrared and CCD detector and direct driving motor are employed for the coarse tracking. When the target is shown in the fine tracking field of view, PZT fast steering mirror and fine tracking CCD are employed for fine tracking. In the coarse tracking process, it is useful to extract the target information from infrared and CCD detector for stable tracking. The coarse-fine tracking cooperative control takes advantage of the fine tracking target deviation, relative movement of the fast steering mirror and the coarse tracking aiming angle to obtain the actual target aiming information. Besides, the cross decoupling controller with low pass filter is designed to reduce the relative distance between the fine tracking system and the coarse tracking system, and the tracking performance of the compound axis control system is improved. Simulation and experimental results show that this method can effectively improve the bandwidth and precision and anti-jamming capability of the system.
