摘要
平台式惯性导航系统依靠由陀螺稳定的机械平台,为导航系统和姿态稳定系统提供测量基准,平台稳定回路是其中事关导航精度的关键部分。对平台稳定回路进行了建模,在仿真的基础上对单闭环、双闭环、数字双闭环三种控制策略分别设计了控制器,并比较了各控制策略的优劣。经过分析比较表明双闭环控制、数字双闭环控制与目前工程上普遍应用的单闭环控制策略相比提高了系统的动态抗扰能力。
Dependence by top stable mechanical platform, platform type inertial navigation system provide the guidance datum for the guidance system and the attitude control system. The platform stabilization loop is essential part affects on navigation accuracy. The modelling has carried on to the platform stabilization loop. The three kind of control policies ： single closed loop, the double closed loop and the digital double closed loop has designed the controller separately, and has compared e-ach control policy fit and unfit quality in the simulation foundation. After the analyzed and compared the double closed-loop control strategy and the digital double closed-loop control strategy with single closed-loop control strategy that widespread application in the present projects , indicated that： first both enhanced system＇s dynamic perturbation performance.
