| 摘 要： | 针对挠性陀螺寻北仪控制力矩产生的需要,设计了力矩电流发生器。控制计算机解算得到的控制电流所对应的控制电压通过ADT800输出给压控恒流源,通过软件控制开关电路实现控制电流的精粗和极性转换,解决了系统对大范围、高精度控制电流的需求。实验测试表明,该电路工作稳定,能满足系统性能要求,可推广应用到其他惯性导航系统中。

| Abstract: | A torque current generator was designed to meet the requirements of north seeker.The control voltage corres-ponding to control current is output by ADT800 to voltage-controlled constant current source,the polarity and thickness conversion of control current are realized through software controlling switch circuit,and a large-range,high-precision control of current demand are solved.Experimental tests show that the circuit is stable,can meet the system performance requirements,and can be applied to other inertial navigation system. |
