| 摘 要： | 采用带有观测器的反馈控制系统设计方法，对平台式惯导系统进行初始对准研究。通过构造一个降维的预测器，利用北向和东向加速度计的测量值重构平台方位对准误差角，同时利用状态反馈改善系统的动态性能，这种方法不需外部信息对平台式惯导系统进行实始对准，仿真结果表明该方法具有一定的对准精度的快速性。

| Abstract: | A design method of state feedback control system with an observer is proposed for the initial alignment of a platform Inertial Navigation System.A design of reduced order observer is made to estimate the azimuth alignment error using the outputs of north and east accelerometers.Mean while,the state feedback method is used to improve the dynamic performance of the system.This method does not need any external information for the initial alignment.Simulation results show that the proposed method has definitely aligning accuracy and rapidity. |
