Embedded Control System for Self Adjusting Scissor Lift
2018 Fourth International Conference on Computing Communication Control and Automation (ICCUBEA), 2018Scissor lifts are used as an alternative to scaffolding and ladders to work in elevated areas, they are very commonly used in warehouses and working sites. But, the random distribution of load on and uneven surfaces on working sites, have accounted for a lot fatal accidents due to lift tip-over.

ROBUSTNESS OF ADAPTATION IN CONTROLLED SELF-ADJUSTING CHAOTIC SYSTEMS
Fluctuation and Noise Letters, 2002It was recently shown that self-adjusting systems adapt to the edge of chaos. We study the robustness of that adaptation with respect to a controlling force. We first use numerical simulations in a modified logistic map. With these, we find that, if the controlling force has a target value of the parameter that leads to periodic dynamics, the control ...

Fuzzy self-adjusting PID controller based network control system
2012 24th Chinese Control and Decision Conference (CCDC), 2012For the existence of interference in network control system, by considering both error and error difference, a fuzzy self-adjusting PID controller based network control system is presented in this paper. In order to correspond with the practical requirements, according to the system error and error difference, the algorithm uses the principle of fuzzy ...

Self-adjusting filling control system forself-grinding drum mills
Collection of Research Papers of the National Mining University, 2022Purpose 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, 1963Summary 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, 1961ABSTRACT 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 ...

Self-adjusting fuzzy controller application for linear induction motor control system
2008 3rd IEEE Conference on Industrial Electronics and Applications, 2008The 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
2009For 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 ...

Searchless Self-Adjustable Adaptation and Control Systems
2002The 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.
