Abstract
The VEGA Launch Vehicle of the European Space Agency performed its maiden flight in 2012 with outstanding success. The control laws flown are based on a mixed SISO/MIMO approach using PID with tuning filters plus a gyroscopic term to deal with coupling in presence of non-negligible roll rate. This paper presents a pure MIMO approach based on an H-Infinity controller. The generated controller is compared with the real implementation and performs better in presence of high roll rates.
