The research team from Control and Avionics Department of Rzeszow University of Technology (RUT) has been working on control systems for many types of flying objects for years. Experiences the team has had during their activity have helped create the control algorithms for a medium‐size flying target (MSFT). Researchers from RUT, together with the small aviation company EUROTECH, have been working on a flying target for artillery. This paper gives a generic view of the system, including airborne and on‐ground parts. But this paper mainly presents the control system that is mounted on the MSFT. The paper describes the generic conception of the control system of the flying target, including control laws used in the control system of the MSFT. Results of simulations and real flight data are also presented. Santrauka Ržešovo technologijos universiteto Valdymo ir kontroles departamento tyreju grupe keleta metu dirba su ivairi u tip u orlaivi u valdymo sistemomis.

The paper presents conception and practical realization of laboratory testing of control system for small aircraft. The stand used in these tests is prepared in Matlab and Simulink environment. Usage of xPC and RTW modules enables the system to perform “Hardware in the loop” real time tests including tests with pilots. As a hardware PC computer equipped with specialized boards, including A/C, C/A, converters and RS232, LPT, CAN 2B data lines was used. The main task of presented stand is to make possible tests of control system introducing new conception of aircraft controlling (e.g. smart control and decoupled control techniques).

The article presents key properties of a module intended to estimate non-measurable state variables of an aircraft (a fixed-wing aircraft). Sample calculations are applicable to the MP-02A Czajka light Optionally Piloted Vehicle (OPV). The quality of flight parameter values’ estimation is illustrated by comparing flight parameters of the MP-02A Czajka aircraft recorded during actual flight with estimated values of respective parameters calculated during simulation of selected sensor faults. This experiment allows to evaluate the usefulness of the analytical redundancy mechanism that determines attitude parameters (roll, pitch and heading angles) and navigational variables (airspeed, altitude and geographic coordinates).

The dynamic growth of general aviation as a mean of transport over medium distances means that people having no extraordinary qualifications or extraordinary physical or mental abilities more often pilot such types of airplanes. This phenomenon creates the necessity of giving planes flying qualities that allow them to be safely piloted by ordinary people. One way of solving this problem is equipping airplanes with fly‐by‐wire control systems that modify their handling qualities. Then the computer included into such control systems modifies the actions taken by the pilot, making the airplane both easier and more comfortable to control. This paper presents sample software tools – control algorithms that allowing an airplane's handling qualities to be improved. They are prepared by the authors and tested on board an experimental plane. That plane was equipped with a prototypical fly‐by‐wire control system, which can modify a plane's responses to a pilot's actions.
