    Abstract: This paper presents an efficient proportional-plus-integral (PI) current-output observer-based linear quadratic discrete tracker (LQDT) design methodology for the non-minimum-phase (NMP) discrete-time system with equal input and output number, for which the minimalized dynamic system contains the unmeasurable system state and unknown external match...

    Abstract: Due to the lack of specific flying quality criteria for UAV (Unmanned Aerial Vehicle), most researchers use the human flying quality criteria to evaluate the UAV flying qualities. This paper, through analyzing the flying performance of the small UAVs before and after the inclusion of the control augmentation systems, has validated the applicability... Show More
