Self-adjusting filling control system forself-grinding drum mills

Collection of Research Papers of the National Mining University, 2022
Purpose of work isan improvement of the controlling efficiency for the processes of self-grinding ores in drum mills by using adaptive settings for the perimeters of the control part of the system. Methodology. For the self-grinding process, the degree of filling of the mill drum is a critical technological variable, i.e. this parameter not only has a

On self-adjusting control systems without test disturbance signals

IFAC Proceedings Volumes, 1963
Summary The report presents and analyses one of the principles for designing an adaptive system to control time-varying processes. According to this principle, in the processes of self-adjusting, the dynamic characteristics of the system (plant and controller) and the effect of some uncontrolled external disturbances are taken into consideration ...

A Review of Self-adjusting Systems in Automatic Control†

Journal of Electronics and Control, 1961
ABSTRACT Problems arising in the application of techniques of automatic control to complex non-linear systems subject to random disturbances may be solved by automatic optimization. A variety of such schemes have been proposed. These are discussed with reference to a performance criterion which is to be optimized; they may be classified as employing ...

A Calibration-Free, Self-Adjusting Stereo Visual Control System

IFAC Proceedings Volumes, 1996
Abstract The purpose of this paper is to describe a self-adjusting, vision-based controller which is able to control the position of a robotic manipulator without explicit calibration of camera parameters. The control strategy is based on the concepts of cyclic switching (Pait 1993) and dwell-time switching (Morse 1995a). With these techniques, it is

Self-adjusting fuzzy controller application for linear induction motor control system

2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008
The mathematical model of linear induction motor (LIM) based on slip frequency type vector control system is established. A self-adjusting fuzzy controller (SAFC) is designed as magnetic thrust adjuster of the motor. The speed of the motor is adjusted by control magnetic thrust of the motor.

Application of Self-adjusting Quantitative Factor Fuzzy Controller in Tank System

2009
For normal fuzzy controllers can’t provide perfect effects when it is used to control the water tank system, this paper adopts a self-adjusting quantitative factor fuzzy controller to deal with this problem. The effects indicate that this controller has the characters of responding quickly, small overshoot and less static errors, and it is practicably ...

The self-adjustable fuzzy sliding mode control for AC speed drive systems

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
The paper deals with a novel method, self-adjustable fuzzy sliding mode control, of a squirrel cage induction motor drive systems with a voltage source inverter. According to the principle of fuzzy logic control and sliding mode control, the theory of this new fuzzy sliding mode control is presented and a mathematical description for induction motor is

Searchless Self-Adjustable Adaptation and Control Systems

2002
The problem of identification and estimation of unknown parameters is one of the most important problems of control theory and practice. However the difficulty of realizing identification procedures consists for one thing in the impossibility of performing a direct parameter control in conditions of uncertainty.

A comparison of the measuring time in self-adjusting control systems

IFAC Proceedings Volumes, 1963
Summary It seems impossible to select the ‘best’ self-adjusting system out of the many proposals, but it is possible to compare them from a certain point of view. In this paper the point of view is the time required in measuring the parameters to be adjusted, considering random input signals. Three devices are compared which adjust one parameter of a
