Nonlinear control theory has received considerable attention m the last decades. As a result, there exists nowadays a sophisticated framework using (differential) geometric methods for dealmg with a large number of controller design problems. The book under review, Nonlinear Control Design, Geometric, Adaptiue and Robust presents according to the back cover of the book “A self-contained introdu...

An industrial weigh belt feeder is used to transport solid materials into a manufacturing process at a constant feedrate. It exhibits nonlinear behavior because of motor friction, saturation, and quantization noise in the sensors, which makes standard autotuning methods difficult to implement. This paper proposes and experimentally demonstrates two types of fuzzy logic controllers for an indust...

In this study, we present an adaptive self-tuning controller (STC) design for small embedded systems. The new free tool-chain for model based control design is based, among other software, on the open simulator Scilab-XCos. After a very short introduction of model based design terms, this article focuses on the code generator and the other programs of the tool-chain. The design concept is demon...

We argue about the importance of embedding the successful mechanism of Inflation in the context of a fundamental theory. We review some of the attempts in this direction made in the framework of String Theory. In particular we report on recent developments in Brane Inflation with emphasis on the fine tuning issue.

This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...

Project Solutions. Increasing responsiveness is often dealt against decreasing another valuable resource. As responsiveness is a quality, the most significant resources in a software project to trade off are scope, cost, time, and other quality aspects. In a lot of systems, namely “embedded systems”, software is an integral part, but only one part of the system. Here trade-offs against hardware...
