van Gool, M.F.C. (author), Mooij, H.A. (author)Servo-analysis techniques, using mathematical models of human control behaviour, are effectively used in studies of the system formed by the human pilot and the flight control system/aircraft combination. Measurement and data analysis techniques for the determination of pilot describing function, remnant and associated information needed in...report 1975

van Woerkom, P.T.L.M. (author)The document contains a general theory towards the observation and optimal control of disturbed, target following aerospace systems. Disturbed, target following aerospace systems eire defined as aerospace systems that are designed to track a moving target system, while they are subjected to external, time-varying disturbances. The first five...report 1976

Mooij, H.A. (author)The introduction of fly-by-wire primary flight control systems in certain categories of future transport aircraft, makes it highly desirable to initiate further studies into handling quality criteria for future guidance in system design and airworthiness certification. The handling quality criteria for such aircraft must be based on parameters...report 1976

Wewerinke, P.H. (author)The outside scene is often an important soiirce of information for manual control tasks. In the context of aircraft control the most important example is the visual approach scene. This study deals with modelling the visual scene perception process on the basis of linear perspective geometry and the relative motion cues and investigates its...report 1978

Smit, J. (author)During a visual approach to landing a pilot uses cues in the visual scene for the control of aircraft attitude and flight path. The accuracy with which some relevant display elements can "be set at a desired, nominal, position was determined in an experiment via the phychophysical "method of adjustment". Furthermore relevant literature with...report 1978

Blom, H.A.P. (author)The problem considered is filtering for Gaussian observations of linear differential systems that are driven by both Wiener processes and marked Poisson point processes. Well-known representations of the MMSE-filter for such a Markov jump-diffusion are a differential for the evolution of its conditional density or differentials for all its...report 1982

Blom, H.A.P. (author)A sophisticated starting point for a probabilistic approach to the radar tracking problem is a Markov jump-diffusion model for the aircraft dynamics, its control and the radar measurements. From nonlinear filtering theory, a closed form description of the evolution of the conditional distribution of this Markov process can be obtained. This jump...report 1983

Joosten, L.J.M. (author), Wakker, K.F. (author)On the proposed satellite-based navigation system NAVSAT, a study has been performed concerning the characteristics of the control segment. Starting from the outcome of earlier preliminary studies of ESA, this study shows that the concept is feasible.report 1985

Blom, H.A.P. (author)The general setup of the evaluation of a radar tracking algorithm in a civil ATC-system has been considered from an operational point of view. Both the present and the potential future use of trackdate has been taken in account. The result is a method to evaluate trackers for ATC on the basis of live-traffic data, under the assumption that a...report 1986

Erkelens, L.J.J. (author)The present flight simulator study has been addressed to the evaluation of the approach path parameters for curved approach paths. A number of seven oblique approach paths has been investigated, varying in both straight final length and oblique angle. The investigation was carried out for various operating minima (decision height, runway visual...report 1987

van Gool, M.F.C. (author), Hoogeboom, P.J. (author)In July, 1988, flight trials have been performed on the newly installed MLS equipment at Manchester Airport (UK), using one of the laboratory aircraft of NLR, a Fairchild Metro II with programmable avionics systems including a basic MLS receiver as an "Avionics Research Testbed". The aim of the tests was to prove that aircraft with basic IFR...report 1989

Blom, H.A.P. (author)Stochastic processes with a decision-directed control are considered as controlled Markov processes, the state space of which is hybrid; i.e. a product of a discrete set and a Euclidean space. This approach yields a mathematical model for many problems of decision-directed stochastic control. In general, the observations made from the "past" and...report 1990

Hoogeboom, P.J. (author)From recorded Distance Measurement Equipment (DME) data during Microwave Landing System (MLS) flight trials performed at London Gatwick Airport (April 21 - 26, 1989) using the NLR Fairchild Metro II Laboratory Aircraft, the position of the aircraft was determined by post-processing and compared with the MLS- and ILS-derived positions. This...report 1990
