Design/methodology/approach - In this study, model predictive controller and linear quadratic regulator are designed and compared within each other for the stabilization of the open loop unstable nonlinear helicopter model. Findings - This study shows that the helicopter is able to reach to the desired target with good robustness, low control effort and small steady-state error under disturbances such as parameter uncertainties, mistuned controller. Originality/value - The purpose of using model predictive control for three axes of the autopilot is to decrease the control effort and to make the close-loop system insensitive against modeling uncertainties.eninfo:eu-repo/semantics/closedAccessModel predictive controlAutonomous vehicleHelicopter controlLinear quadratic controllerVelocity controlArticle10.1108/AEAT-01-2015-00042-s2.0-849916878808176N/A81088WOS:000386784900013Q4
