“…Adaptivity of the limiters relies on the principle that the maximal shaft speed or exhaust gas temperature of the engine can be adjusted according to flight conditions or Figure 2: The designed situational control system for gas turbine aeroengines. 4 International Journal of Aerospace Engineering environmental conditions. The expanded situational control system developed in Figures 2, 3, and 4, as framework architecture, is the foundation of an intelligent FADEC or i-FADEC to be implemented and tested on a small turbojet engine.…”

“…Small gas turbine aeroengines are specifically characterized by compact dimensions weighing from 0.5 to 50 kilograms and relatively high static thrust outputs in the range up to 1500 N, producing very high power to weight ratios as defined in [3]. Such engines represent a great potential for commercial applications in different areas of aviation for propulsion of drones and small UAVs described in [4], as well as small airplanes or helicopters [5]. Because of compact dimensions as well as cost-effective operation and production, these engines can serve as experimental testbeds for research purposes as can be seen in the work of Benini and Giacometti [3], where a small turbojet engine with static thrust of 200 N has been designed.…”

Improvements in reliability, safety, and operational efficiency of aeroengines can be brought in a cost-effective way using advanced control concepts, thus requiring only software updates of their digital control systems. The article presents a comprehensive approach in modular control system design suitable for small gas turbine engines. The control system is based on the methodology of situational control; this means control of the engine under all operational situations including atypical ones, also integrating a diagnostic system, which is usually a separate module. The resulting concept has been evaluated in real-world laboratory conditions using a unique design of small turbojet engine iSTC-21v as well as a state-of-the-art small turbojet engine TJ-100. Our results show that such advanced control system can bring operational quality of an engine with old turbocompressor core iSTC-21v on par with state-of-the-art engines.

“…At Faculty of Aeronautics we have been aimed not only on classical airplanes but on multirotors application predetermined for monitoring purposes too. [1] In the past, we have developed many own untraditional multirotors concepts. When the small aircraft position, attitude and heading determination task was solved, our new task became to construct camera gimbal and to stabilize and control it to be able to obtain sharp photos of chosen object of interest.…”

The paper deals with approaches in controlling of a complex electro-mechanical system. The proposed system is servomotor as a part of camera gimbal intended for UAVs (Unamnned Aerial Vehicles). Camera gimbal is a non-linear system with hysteresis and transport delays. The paper deals with experimental data driven method of servomotor modeling and also with classical control algorithms method and control algorithms based on fuzzy logic. The presented methods, approaches and applications are directly usable for similar electro-mechanical systems. The presented solution is cost effective, precise and fast using advanced algorithms.

This paper proposes a state feedback controller for the attitude stabilization problem of quadrotors. The quadrotor attitude is represented by unit quaternion and disturbance of the attitude model is taken into consideration. A robust controller is synthesized via H∞ optimal design approach. Solving the nonlinear H∞ optimal control problem using state feedback is meltdown to finding a solution to a Hamilton-Jacobi inequality. Based on the quadrotor attitude dynamics, an appropriate parameterized Lyapunov function is selected and the corresponding state feedback controller is derived. Then the parameters are found from a Hamilton-Jacobi inequality. The resultant state feedback controller can lead to closed-loop nonlinear system having L2-gain less than or equal to a constant γ, and establish the asymptotically stability of the closed-loop nonlinear system without external disturbance. The simulation provides the results to show the stability and the robust performance against to disturbance. I. INTRODUCTIONIn recent years, research in control of Quadrotor has been growing due to its simplicity in design and low cost. Quadrotors have several advantages over fixed-wing aircrafts, such as take-off and landing vertically in a limit space, easy hover over fixed or dynamic targets, which give them efficiency in applications that fixed-wing aircrafts cannot do, and they are safer [1][2] [3]. Quadrotors can be used to perform several tasks in the applications of dangerous area for a manned aircraft in a high level of accuracy. It can be used in different applications, such as inspection of power lines, oil platforms, search and rescue operations, and surveillance [4] [5]. Control of a quadrotor helicopter is a challenging task. The difficulty comes from the complexity of modeling its dynamic system, their underactuated mechanism, and various external disturbances [5] [6].The attitude control is to stabilize the orientation of quadrotors, which is a first step towards more complex control systems [5]. Researchers have been focusing on design and implementation of many types of controller to control the attitude of individual quadrotors. A nonlinear proportional squared control algorithm was proposed in [7] for attitude control. The controller was implemented to a linear quaternion simulator of quadrotors. Elias R. et al.[8] presented a nonlinear quaternion mathematical model to describe the attitude dynamics of quadrotors. They implemented a LQR gain scheduling controller for trajectory tracking and attitude stability tasks. A bounded control law was presented to obtain
