Abstract Some activities at the DFVLR which deal with system modelling and performance evaluation under uncertainty, as well as feedback control applications, are reported. The examples are mainly drawn from activities of the research department ‘Flight Mechanics / Guidance and Control’ where active control of aircraft and helicopters plays a central role. Uncertainty is related to system parameters, disturbances, operational state and operator behaviour. In this respect, DFVLR activities in applied nonlinear parameter identification, on-line wind measurement and prediction, stochastic simulation, and sensor diagnosis via analytic redundancy are briefly described. Applications of feedback control concern model-following control for inflight simulation, robust stabilization of high-performance aircraft, aircraft flutter stability augmentation via active mode decoupling, and active damping of mechanical light-weight structures based on finite-element modelling.
