Abstract

This research aims to develop trajectory controls for a levitation platform which is powered by rocket fuel. This control task is to regulate the platform for 3D trajectory followings and suspension in the air, which is different from that of the most rocket systems. To cope with the challenges of slow thrust response and coupled vehicle dynamics, we proposed a control system that consists of 4 independent loops for the height, yaw angle, x-position, y-positions, respectively. The developed controllers include 4 PID compensators for the flow rate throttling system, and four double phase lead and two lead-lag compensators for the vehicle dynamics. According to the simulation results, the levitation platform can follow a designated trajectory well when there exist external torques disturbance. (both 1 N-m step inputs and 0.1 N-m Gaussian distributed input) and 2% thrust force oscillations.
