Binary Batch Distillation Column Pilot Plant available with us was running with Local Programmable Logic Controller (PLC). Performance enhancement of plant is done with two different aspects that are 1. To operate plant by different modes of control that is by different remote controllers. 2. To enhance the performance of product point of view that is quality of product, time required for the process...
In order to solve the problems that the performance of Internal Model Controller may decline in its industrial plant implementation process which is often caused by constraints, In this paper we applied NPSO algorithm on the internal model control system with constraints. We optimized the parameters of Internal Model Controller by utilizing the advantages of NPSO algorithm which has a small amount...
The confluence of modern genetic manipulation techniques, powerful measurement technologies, and advanced analysis methods is enabling a new area of research in which systems and control notions are used for regulating cellular processes at the gene level. This presentation describes novel analytical and experimental work that demonstrates how de novo control systems can be interfaced with living...
A class of dual-rate system with a fast control updating rate and a slow output sampling rate is considered. Lifting technology is applied to derive lifted state space model and a subspace equation for dual-rate systems. From the subspace equation, the dual-rate predictive control law is calculated from a set of input/output (I/O) open-loop experimental data and, thus, this approach is data-driven...
A kind of auxiliary device for ankle rehabilitation based on ball pin vice is designed and developed. The device has two degrees of freedom, but it can achieve approximatively the three-dimensional movement of the bionic ankle. When the device is used for auxiliary ankle rehabilitation, which only leads ankle to rotate not to move, and its structure is very simple. The ball pin pairs are adopted as...
With glass fiber manufacturing industry as an example, studied the design and application of automatic logistics system based on 2-Dimensional Bar Code. The system through the analysis of information flow in the process of production, designed and studied the application in the production process about Fieldbus Control System, Programmable Logic Controller, Manufacturing Execution System, Enterprise...
In recent years, the trend in large-scale equipment of grinding classification process becomes increasingly common in metallurgical plant. This trend raised the new requirement of much higher efficiency and performance precision in large-scale griding process. Taking into account the peculiarity of strong disturbances and wide operation range in most of domestic concentration plant, several practical...
Non-fragile robust control problem of a fan system is studied. It is pointed out that this problem of the fan system is really a non-fragile robust performance problem, the problem of the fan control system with both non-fragile robust stability and performance requirements(bandwidth and other performances). It is also suggested that the design of the non-fragile robust performance of the fan system...
In this paper, based on the results of complex analysis, we address and analyze some conclusions proposed by V.Blondel et al., which concern the simultaneous stabilization of three linear systems and a special bistabilization problem, named as “Chocolate Problem”. As for the simultaneous stabilization problem of three linear systems, it is shown that there is a slight flaw in the sufficiency part...
In this issue of IEEE Control Systems Magazine, we speak with Jie Huang, who is a professor and the chair of the Department of Mechanical and Automation Engineering at The Chinese University of Hong Kong. He studied power engineering at Fuzhou University from 1977 to 1979 and circuits and systems at Nanjing University of Science and Technology (NUST) from 1979 to 1982. He received a master's degree...
In order to adapt to complex industrial production environment, a remote monitoring system based on the open fieldbus CC-Link is researched. Through the establishment of the CC-Link network, as a remote device station and an intelligent device station, the touch screen and industrial robot are set in the network, a touch screen remote monitoring of industrial robot is achieved. The method can solve...
We present a lightweight tool for coordinating tool usage in a structured and unobtrusive manner allowing for the formal description and implementation of development cycles with minimal human intervention. This tool, here and after referred to as “Path∗” seeks to provide a minimal yet powerful framework for tool coordination by scripting actions to be triggered on events such as disk writes to a...
Possibilities of selecting parameters of characteristic polynomial of differentiating filter are considered. The selection should provide required quality of the filter and fast response of automated control system. Roots of the characteristic equation of the automated control system are dependent on the requirements to quality of the transition processes. Area occupied by possible values of the polynomial...
The gradient of a scalar function is frequently used in various areas of mathematics. In informatics it can be used, for example, in the process of learning procedure of many control systems. The key observation is that gradient, if it is a non-zero vector, is a vector in the direction of greatest rate of the scalar function. In this contribution we show a method how to determine the direction(s)...
In industrial automation, multi-mass system controlling is a common problem. Varying or unknown parameters, especially friction, make the control problem more difficult. The main purpose of this paper is to design an non-linear multi-stage PID controller to solve the problem above in multi-mass elastic torsional system. The preliminary of elastic torsional system is first analyzed. Then, nonlinear...

In multivariable processes, control structure selection represented as the pairing of manipulated variables and controlled variables is a major concern during the design of multi-loop regulatory PID control system. Each pairing method has its application scope, and it is necessary to analyze and evaluate the closed-loop application effect of the system pairing. Based on the dynamic transmission ratio...
In order to restrain the adverse influence of speed mutation and torque ripple when brushless dc motor runs at the commutation moment, at the same time, for the sake of avoiding the fact that traditional PI control tragedy highly depends on the precise mathematical model of the controlled system, this paper puts forward a kind of control tragedy of domain self-regulating fuzzy control. At first, the...
