Robust gain-scheduled blending control of raw-mix quality in cement industries

Alireza Karimi, Michael Amrhein, Vinicius De Oliveira

This paper addresses the control of the blending process in cement industries. This process can be modeled by a nonlinear multivariable system with large parametric uncertainty. Using a specific transformation, a linear parameter varying (LPV) model with s ...

Robust Controller Design by Convex Optimization based on Finite Frequency Samples of Spectral Models

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not guaranteed for the frequencies between the frequency samples. In this paper, all possible ...

New Approach for Simple and Rapid Shape Measurement of Objects with Surface Discontinuities

Sai Siva Gorthi

A new approach for unwrapping phase maps, obtained during the measurement of 3-D surfaces using sinusoidal structured light projection technique, is proposed. “Takeda’s method” is used to obtain the wrapped phase map. Proposed method of unwrapping makes us ...

Frequency response identification of the dynamics of a Tokamak plasma

Jonathan Bryan Lister

In this paper we describe the application of an H-infinity system identification procedure to a Tokamak. The work is motivated by the need to create linear models which are suitable for controller design and which may be used to validate different models d ...

Nonlinear separation of forward and backward running waves in elastic conduits

Nikolaos Stergiopoulos, Jean-Jacques Meister

A new method for the separation of forward and backward running waves in elastic conduits, with possible extension to the arterial system, has been developed. The mathematical model is based on the one-dimensional flow equations which allow the treatment o ...
