In January 2014, a new control law, known as adaptive control, was uploaded on board the CNES scientific satellite "Picard" dedicated to studying the sun. This satellite, on a mission beyond its design life expectancy, has lent itself to demonstrate these innovative algorithms. Challenges: improving performance and especially shortening the design time.
