Under the condition of strong connectivity, the formation keeping problem of missile formation based on high-order fully actuated system is studied. The time-varying controller of the system is designed for the formation tracking of missile formation and disturbance suppression by upgrading the first-order model to the second-order model and using the parametric approach. The numerical simulation experiments of the system are completed with the introduction of bounded random disturbances. The motion trajectory, position tracking error, velocity tracking error and control force output of the missile formation are analyzed, and the final steady-state error is basically stabilized within 0.1, and the control force is controlled at about 2000 N during the formation holding phase.

In this paper, the model of a novel liquid-circular angular accelerometer is studied. Due to the absence of theoretical model of liquid-circular angular accelerometer, a subspace identification method(SIM) based on Akaike Information Criterion(AIC) is chosen for model identification of angular accelerometer. The proposed identification method is tested on a liquid-circular angular accelerometer prototype. The experimental results indicate that SIM could obtain a more accurate model than least square method, with a degree of fitting above 90%. In addition, SIM possesses good repeatability and stability. The experimental model identified by SIM in this paper can be applied in engineering practice.

In this paper, a small dual-band antenna has been proposed for moving terminal applications, which is fed by microstrip line and consists of feeding line, partial ground plane, semi-circular ring strips, reversed C-shaped, e-shaped and parasitic branches. The bending branches are employed for the designed antenna to increase the path of current, which is beneficial to reduce the size of the proposed antenna. In addition, the parasitic branches are loaded by coupling capacitance to provide another band for the proposed dual-band antenna, which miniaturizes the designed antenna and makes the operating band easy to be adjusted. By modeling and optimizing the structure of the proposed dual-band antenna in the HFSS, the results show that the proposed antenna can operate at 3.52 GHz and 5.25 GHz. Moreover, the developed dual-band antenna has omnidirectional radiation patterns at both operating bands and got a good total realized gain. Therefore, the designed dual-band antenna is very appropriate for the small moving terminal applications.
