船舶力控减摇鳍伺服系统研究

The Study of Lift Feedback Stabilizer Servo System on Ship

针对船舶力控减摇鳍伺服系统，运用控制理论考虑混合灵敏度问题设计了控制器，由于混合灵敏度问题模型、权函数的选择、系统奇异性对等实际问题是控制理论应用于实践的关键问题，因此本文结合船舶力控减摇鳍伺服系统着重对这些问题进行了研究，这种思想对于将控制理论用于其它系统设计也有一定的参考价值，同时本文通过仿真分析，将控制器与用LQG方法设计的控制器的效果进行了比较，证明了控制应用于系统的优越性。

This paper investigates robust control problem in the view of the lift feedback fin stabilizer servo system on ship; the controller is designed when mixed sensitivity problem is considered. Mixed sensitivity problem , choosing the weighting functions, system singularity, etc. are studied in the view of the lift feedback fin stabilizer servo system on ship because they are very important if controller is designed to a certain system according to the control theory. The idea is valuable when designing a controller by other system. The control advantage is proved by comparing with another controller which is designed by LQG method. System simulation results are analyzed.
