%0 Journal Article %T DISCRETE-TIME VARIABLE STRUCTURE CONTROLLER FOR AIRCRAFT FLIGHT ANGLE TRACKING %A Iskrenovic-Momcilovic %A Olivera %J - %D 2014 %X Sa£żetak The paper presents the longitudinal, short-period aircraft dynamics and its application on the climb angle tracking. For the aircraft flight angle tracking the stable system centre technique is developed for controlling the output in a discrete-time non-minimum phase causal system using the sliding mode control. The developed discrete-time stable system centre technique transforms the output tracking problem to a corresponding state variable tracking problem by asymptotically identifying the ideal internal dynamics for the unstable internal states of a discrete-time system. A numerical simulation example is given to show the effectiveness of the method %K discrete-time non-minimum phase system %K stable system centre %K sliding mode control %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=191519
