Abstract : A study is described that compares the capability of a fuzzy logic controller with a classical controller P+D (proportional plus derivative). The model used for this investigation is the attitude control of a microsatellite launcher, during the first stage of flight. This model has been chosen because perform a very unstable plant, the launcher is understood without stabilization surfaces and only the body is considered as generator of aerodynamics forces. Movable-nozzle TVC (Thrust Vector Control) will be used as flight control device.
