“…W trakcie dobiegu system wykonuje zadania stabilizacji kursu. Po spadku prędkości poniżej prędkości bezpiecznego hamowania (Ub = 70 km/h) następuje uruchomienie hamulców kół głównych (braking) i zatrzymanie samolotu [6]. Typową trajektorię lądowania przedstawia rys.…”

“…Model-following design technique is a well-known method for a control system synthesis, and it is very often used in design practice (Astrom and Wittenmark, 1989;Kreindler and Rothschild, 1976;Huang and Tylock, 1993;Stevens and Levis, 2004). In this project the modified version of the direct model-following method is applied, which was described in the previous publications (Tomczyk, 1999b;Gruszecki and Tomczyk, 1999;Tomczyk and Gruszecki, 1999). This method is chosen for shaping dynamic properties and handling qualities of the flying laboratory as a very useful solution from didactic point of view.…”

PurposeThe main targets of the work are analysis and simulation of flying laboratory performance. In particular, synthesis of control system for handling qualities change and evaluation in flight are taken into consideration.Design/methodology/approachModification of handling qualities is obtained by applying indirect flight control system (FBW). The properties of the optimal controller are calculated through the indirect (implicit) model‐following method. In particular, the modified version based on the computer simulations is used.FindingsCalculation and simulation concern the synthesis of desired handling qualities of the general aviation aircraft PZL‐M20 “Mewa” equipped with indirect (FBW) experimental flight control system. Results of the simulation show that the flying laboratory has the same properties as modeled aircraft, and it is possible to say that handling properties concern attitude orientation of the experimental aircraft is similar to modeled commuter aircraft.Practical implicationsThe result of research can be implemented on a project of the flying laboratory based on general aviation aircraft PZL M20 “Mewa”.Originality/valueThe paper presents the practical approach for synthesis of the “Simplified total in flight simulator” performance which can be used for analysis of handling qualities of general aviation aircraft equipped with FBW. Research of this type focuses on military and transport airplanes however, there are no published works in the area of small aircraft so far.

“…Autonomous aircraft landing requires accurate control over the flight trajectory in the presence of wind and gusts near the ground. In some cases, automation of UAV landing requires measurement of altitude above ground level (AGL) with an accuracy of 0.2m (Tomczyk et al, 1999). However, the current standard GPS system only provides a position accuracy of approximately 10m (with 95% confidence) in the horizontal direction and 15m (with 95% confidence) in the vertical direction; in addition, GPS can be easily compromised in some hostile environments (e.g.…”
