摘要
平台式惯性导航系统是由惯性稳定系统组成框架式平台,为姿态稳定系统和导航系统提供精确的测量基准.惯导平台稳定回路是保障导航精度的关键部分.针对稳定回路设计控制器时,发现传统PID控制有抗干扰能力不强、控制参数易改变等缺点,将自适应模糊控制方案引入平台稳定回路的双闭环稳定回路设计中.通过对系统仿真结果表明,该控制器的自适应能力和抗干扰能力都优于经典的PID控制器,理论上证明了模糊控制方案在平台稳定回路控制中的可行性,具有一定的工程应用价值.
The platform type inertial navigation system, which comprises an inertial stabilization system based on a frame type platform, provides accurate reference for the measurement of attitude stabilization system and navigation system. The stable circuit on a navigation platform is a key part to guarantee the navigation accuracy. In the design of a controller in the stable loop, it is found that traditional PID control has shortcomings, such as weak anti-interference, and chargealhe control parameters. This paper applies an adaptive fuzzy control scheme to the double closed-loop stable circuit design. The simulation results indicate that the controller＇s adaptive capacity and anti-interference ability are better than the classical PID controller, proving theoretically that this fuzzy control scheme is feasible for the control over the stable circuit of a platform and has a certain value in engineering application.
