Digital Tow Target Altitude Control System Based on Complementary Kalman Filter

针对掠海恒高飞行拖靶系统在超低空飞行高度控制精度上的技术要求,设计了基于Kalman互补滤波的全数字高度控制系统的结构及控制方案;该方案通过采用Kalman互补滤波来处理高度信号,提高了系统的控制精度;同时,全数字化设计使得系统具有较好的可移植性,提高了使用效率。仿真分析与试飞实践表明:基于互补滤波的数字拖把高度控制系统精度高,使用效率高,且具有较强的抗干扰能力。

In view of the requirements of high height precision for super-low altitude tow target, the structure and the control method of the digital altitude control system are designed, in which the altitude signal is dealt with the algorithm of complementary Kalman filter to improve the control precision. Simulation flight-test results show that the system has the performance of high precision and strong anti-interferences which can fulfill the design requirements. The digital design enables the system to have a better portability and improves the service efficiency.
