Abstract

"The aim of the study was to examine the extent in which verbal feedback (positive
and negative) affected the collective efficacy, and to what extent an increase in collective efficacy
would affect the propensity to social loafing in a sport group context where individual
effort is not perceived as identifiable. 66 sports students conducted an interval of one-minute
maximum effort on the bike ergometer under individual conditions. Participants were then
randomized into teams in which half of them received positive feedback, while the others
received negative feedback, before they then carried out three trials under collective conditions.
The participants’ belief in the team’s victory chance was reported ahead of the second
and third attempt. The results show that feedback affected the collective efficacy, but there was
a non-significant difference in performance between the groups."

Abstract

This open access Brief introduces the basic principles of control theory in a concise self-study guide. It complements the classic texts by emphasizing the simple conceptual unity of the subject. A novice can quickly see how and why the different parts fit together. The concepts build slowly and naturally one after another, until the reader soon has a view of the whole. Each concept is illustrated by detailed examples and graphics. The full software code for each example is available, providing the basis for experimenting with various assumptions, learning how to write programs for control analysis, and setting the stage for future research projects. The topics focus on robustness, design trade-offs, and optimality. Most of the book develops classical linear theory. The last part of the book considers robustness with respect to nonlinearity and explicitly nonlinear extensions, as well as advanced topics such as adaptive control and model predictive control. New students, as well as scientists from other backgrounds who want a concise and easy-to-grasp coverage of control theory, will benefit from the emphasis on concepts and broad understanding of the various approaches.
