This paper proposes an efficient Tracking method for velocity control of an electro-hydraulic servo system (EHSS) in the presence of flow nonlinearities and internal friction. The tracking method controller is a kind of feedback error learning structure. In the proposed method, the Feedback Error Learning (FEL) algorithm is used to control the velocity. There is no need to compute the system ja...

This paper presents both, the design and the development of a monitoring and control system via web for a closed microalgae crop and the results that were gotten using the strain Haematococcus pluvialis. The research was done at Sabana University (Colombia) and it aims to quantify the kinetic growth associated to the increment of biomass and the development of red pigment inside the cells when ...

Abstract: fabricated. Modifications carried out in different parts of the old system in order to control mostof the growth parameters with more accuracy. The fabricated system was used to grow sapphiresingle crystals with almost 10 mm in diameter and 50 mm in length. The crystallinity andstructure of the grown crystals were characterized by computer aided single crystal X-raydiffraction techniq...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...

This paper discusses the demands for proper computer aided control system design tools for mechatronic systems and identifies a number of tasks in this design process. It puts the contributions to the session in perspective and describes how the papers in this session (partly) contribute to a solution. Some issues not addressed in the session are discussed and the current state-of-the-art as pe...

Deadlock can occur wherever multiple processes interact. System deadlock is a serious problem in a multiprogramming environment. The approaches to this problem can be divided into three categories: (1) prevention, (2) detection and recovery, and (3) avoidance. This paper proposes a variation of the first approach, partially applying ideas developed in the second and third approaches. This is an...
