MEMS (micro-electro-mechanical system) accelerometers and gyros, performant and robust processor for embedded systems, as well as compact but intelligent and high-performant electro-mechanical actuators. This development is mainly due the availability of a number of new affordable, reliable and high-quality components, e.g. Automatic flight control functions and navigation aids previously only available in commercial airliners can now be found in many general aviation autopilots. In the last decades, an increased digitalization of the avionics in commuter, business and general aviation aircraft has taken place. Increased Digitalization of CS-23 and UAV Avionics Utilization of the advantages of model-based system and software development and of strategic partnerships to reach and go beyond the state-of-the-art of CS-23 digital flight control.A single modular and configurable system providing necessary functionalities with guaranteed stability, performance and robustness characteristics for a large range of automatic flight control applications, fixed-wing aircraft configurations and sensor environments.Research and development driven by increased importance and availability of automatic flight control for manned and unmanned aircraft. ![]() The controller structure provides an interface for incorporation of adaption laws or sensor-based nonlinear control methodologies to account for uncertainties or fault scenarios as structural changes caused by damages. To the requirements driven development, the consideration of the above mentioned real system effects, which highly influence inner loop control performance and robustness, is incorporated into the structural as well the gain design process. gain sets) as well as the adjustment of the envelope protections for aerodynamic and structural integrity. A high degree of automation in the Gain Design Process allows to easily adjust the configuration-specific (aircraft dynamics) and application-specific (performance requirements) controller parameters (e.g. Generic interfaces facilitate the application of the controller structure in multiple aircraft configurations. Since the inner loop controller relies highly on the aircraft dynamics and configuration setting emphasis is given to the development of a generic controller structure and highly automated gain design process that allows an easy adaption to different aircraft configurations. Weight and balance (center of gravity position influence)Īt the Institute of Flight System Dynamics, research is conducted towards an inner loop controller that is applicable to multiple standard aircraft configurations such as fixed wing CS-23, General Aviation, as well as Fixed Wing light UAV.Actuator dynamics (rate limitations, dead zone effects etc.).Time Delays introduced by avionic system. ![]() The inner loop controller has to cope with the most challenging requirements on controller performance and dynamics as well as with the highest requirements on reliability and robustness against model uncertainties and disturbances as The inner loop controller constitutes one of the most critical parts of the automatic control chain.
