Auslegung von Autopiloten durch Zustandsrückführung / The design of autopilots by state feedback

Abstract

The exceptional high requirements with respect to safety and precision for flight control systems, have to be maintained also for the future noise reduced sleep approaches. For this task, a new concept of a flight controller was developed at Manuskripteingang: 28. Juli 1977. * Nach einem Beitrag zum Aussprachetag "Regelungssysnthese im Zustandsraum" der VDI/VDE-Gesellschäft Meß-und Regelungstechnik am 14. und 15. Februar 1977 in Frankfurt am Main. ') Unabhängig von der prozentualen Verteilung der Unfälle ist das Flugzeug, bezogen auf die Transportleistung (Passagierkilometer), eines der sichersten Transportmittel. the Bodenseewerk and checked in flight tests. For the example of this autopilot, problems are discussed, which occur in consequent application of complete state feedback. Points of main effort are besides the economic realization, the limitations of the states to be fed back, the open loop control, disturbance compensation and a combined design with pole assignment and cost function. Besides control accuracy, also flight operational and psychological points of view are important for the choice of the cost criterion.
