Development and Ground Test of Flight Control System for Sounding Rockets

摘要

In this thesis an IMU-magnetometer-Pixy camera sensors configuration with a multiplicative extended Kalman filter (MEKF) for sounding rocket attitude estimation system is developed and simulated In the simulation the sensor data is generated by the sensor model and rocket dynamic model The pitch and yaw angle of the rocket can be estimated by the MEKF within the accuracy of ±0 9° and ±3° from the noisy sensor data The ground test platform for testing reaction control system (RCS) and the online optimization-based controller for sounding rocket attitude control is also setup The state estimation of the test vehicle is obtained by an IMU and a laser scanner with an extended Kalman filter executing on Robot Operating System (ROS) installed in an Odroid XU4 embedded system The thrusters of RCS perform an on-and-off control to de-spin the test vehicle and control it to the desire pose Before the implementation of the control system a software-in-the-loop (SITL) simulation is also developed in ROS which can provide a realistic and convenient environment for software integration
