Multiple Model Switched Repetitive Control
No full textA multiple model switched repetitive control (RC) framework is developed for a general class of system and widely used RC update structure. This guarantees stability and robust performance under the assumption that the true plant model belongs to a plant uncertainty set specified by the designer. A comprehensive design procedure for the candidate model set and RC update is presented based on novel application of gap metric analysis to RC, and switching of the corresponding RC schemes is achieved efficiently using a bank of Kalman filters
Constrained Point-to-Point Iterative Learning Control with Experimental Verification
No full textIterative learning control is a methodology applicable to systems which perform the same operation repeatedly, where the task is the tracking of a specified reference trajectory defined over a finite time duration. Here the methodology is instead applied to the point-to-point motion control problem in which the output is only specified at a subset of time instants. The iterative learning framework is expanded to address this case, and it is shown how the extra design freedom this set-up brings allows additional input, output and state constraints to be addressed. Experimental results illustrate the practical benefits of the proposed approach, and confirm the performance and accuracy that can be achieved

Christopher Freeman : Social science entrepreneur
No full textThis paper focuses on Christopher Freeman's contributions to the field of innovation studies. First, we consider his role as the creator of various organisational and intellectual frameworks crucial for the field's development, including the main research activities he initiated. Next, we examine the publications by Freeman that these activities led to. A database of surveys of the innovation literature, assembled from articles in handbooks covering this area, is used to identify the most influential of his writings for this field. In addition, citations to these works in scholarly journals are analysed in order to examine the nature and extent of his influence on other scholars. The final section sums up the evidence regarding Freeman's influence on the field's development. A list of Freeman's scholarly works is included as Appendix B
