Prins, J.J.M. (author), Dieleman, P. (author), de Jong, H. (author)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...report 1989

Prins, J.J.M. (author), Pronk, C.N.A. (author)In the framework of ESA's Columbus programme, Europe has to master new space operations such as remotely and/or automatically controlled rendezvous and docking (RVD) and manipulation. The need for a test bed for development and verification of the critical proximity operations involved was identified. This report presents the results of a study...report 1985

Bosgra, J.A. (author), Prins, J.J.M. (author)The first part of the paper presents the results of measurements on torque and force irregularities of running reaction wheels. Six different, current technology European wheels, both with ball- and magnet bearings, and with d.c. and a.c. drive motors are examined. Time-domain behaviour around zero wheel speed as well as noise at certain...report 1982

Prins, J.J.M. (author)Torque and force irregularities of running reaction wheels were studied. In this first part of the study report results from noise measurements at constant wheel speeds on various types of current technology European reaction wheels, both with ball- and magnet bearings and with DC or AC drive motor, are presented. The measured noise in radial...report 1982

Prins, J.J.M. (author)The increasing power of on-board processors allows more freedom in the design and operation of reaction wheel control systems. This report discusses several performance and implementation aspects of the operation of wheel systems which have their own internal feedback control system. A model following control concept is found to be superior. The...report 1982

Prins, J.J.M. (author)The existing fine attitude system of the Astronomical Netherlands Satellite was designed on the basis of conventional digital control techniques. The possibility of a more advanced approach is presented in this report. As an example, an alternative control algorithm for the scan mode has been developed with the use of state estimation and state...report 1976
