In fact, the control problems of the sonar array posture are track control problems. So On the basis of theoretic study, the author designs the robust output track control of the posture of the sonar base with regulable parameter and applies the study results of measurable disturbance decoupling and robust output track to the minehunting sonar array posture control, a robust control strategy with disturbance decoupling, output track and compensation for uncertainty is found.

All of the submarines had the MGK-400 Rubikon sonar system. In the early 1980s, the Rubikon sonar was replaced by the MGK-500 Skat system, which used a much more capable digital computer and advanced signal processing.

所有这些潜艇都有MGK-400 Rubikon声纳系统，在80年代早期，Rubikon声纳被具有更强数字计算机和先进信号处理能力的MGK-500 Skat系统取代。

Due to the moving base existence of the minehunting and the frame structure characteristic of the sonar array,a new modeling thought in which the boat body coordinates is regarded as moving coordinates and the whirligig equation of sonar array compared with the self coordinates is founded on the basis of the Eulers theorem and the coordinate transform is introduced. The dynamic equations of minehunting sonar array with the state matrix form are founded by settling the dynamic models with the vector form. So it offers theory foundation for analyzing the dynamic characteristic and designing robust control.
