陀螺寻北仪阻尼步进限幅法

为提高摆式陀螺寻北仪的限幅效率,在步进迭代法的基础上提出了阻尼步进限幅法.首先分析了步进迭代法的两个关键点:步进迭代以及撞边情况的处理;然后详细地叙述了阻尼步进限幅法在撞边情况处理的新方案并给出了新方法的实现算法;最后通过对步进迭代法与阻尼步进限幅法的对比仿真,验证了阻尼步进限幅法的限幅效率比步进迭代法的限幅效率高的结论.阻尼步进限幅法不需要增加已有的陀螺寻北仪的机械结构,只需要对系统的控制程序进行更改即可投入工程使用.

Damping Step Method of Pendulous Gyroscopes

In order to improve the damping efficiency of pendulous gyroscopes,a method named damping step is put forward.First,the two main steps of step iterative method are analyzed,i.e.how to judge the inverse point and follow the inverse points.Then,a new method to solve collision problem of pendulous gyroscopes is expounded and the algorithm is given.Last,contrast simulation is done to demonstrate that the damping efficiency of the proposed method is better than that of step iterative method.It''s not necessary to add system hardware,by changing the system control programs,the proposed method can be put into practice.
