De regeling van het Mach getal in de hoge snelheids tunnel van het NLR

The High Speed wind Tunnel (HST) of the National Aerospace Laboratory NLR is one of the major transonic windtunnels and is used for aerodynamic research on scale models. The measurements require the control of the Mach number. Two kinds of controller tasks can be distinguished: keeping the Mach number constant, and realizing a different Mach...

The real-time Hermes robot arm simulator: HSF-P

The Hermes manipulation system (HERA) is a sophisticated space manipulator system, which has to perform tasks ranging from berthing to tool operation in various operational modes from fully automatic to purely manual. The HERA system main contractor is Fokker Space & Systems B.V. (FSS). Development and qualification of such a space-based...

Dynamics modelling, simulation, and control of a spacecraft/manipulator system

Four well-known formalisms for mathematical modelling of the dynamics of a spacecraft/manipulator system are derived from the unifying d'Alembert principle. The Newton-Euler formalism is discussed in more detail, as it allows efficient numerical simulation. An algorithm is defined for the control of the manipulator end-effector motion in...

Preliminary experiments with an electro-osmotic heat pipe laboratory model

Preliminary experiments have been performed with a laboratory model of an electro-osmotic heat pipe filled with ethanol. With dismounted electro-osmotic pump, the heat transport through the pipe and the temperature distribution along the pipe wall have been measured. The measurements have been performed as a function of the temperature...

Survey of modern control and observation theory for disturbed, target following aerospace systems. Part one: Basic theory

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...
