3-DOF Position and Orientation Control of an Air Flotation Platform for Spacecraft Ground Microgravity Simulation by Using Double Closed-Loop Cascade PIDnn

<div>(a) Schematic diagram of space station and ground simulation platform. The AAR-2 is a free flying robot used in the space station cabin to assist astronauts in some space missions. This robot can use the microgravity simulation air flotation platform to simulate the 3-DOF plane motion on the marble table. (b) Actual experimental platform.</div>
