Different approaches have been used in order to represent and build control engineering concepts for the computer. Software applications for these fields are becoming more and more demanding each day, and new representation schemas are continuously being developed. This paper describes a study of the use of knowledge models represented in ontologies for building computer aided control systems design (CACSD) tools. The use of this approach allows the construction of formal conceptual structures that can be stated independently of any software application and be used in many different ones. In order to show the advantages of this approach, an ontology and an application have been built for the domain of design of lead/lag controllers with the root locus method, presenting the results and benefits found.

Most conventional design processes produce documentation as a by-product: design is done within an environment or collection of tools and the design outputs, models, diagrams, results, etc are gathered together along with commentary (usually with hindsight) into some kind of document at the end of the process. Inspired by ideas taken from literate programming and notebook interfaces to design tools, a prototype document centred design document has been developed. In such an environment, the document is the main product and the design is a by-product of documenting the design. By implementing the framework components of the system in Java and by using the extended markup language (XML) to encode the contents of the documents, the system is made platform neutral and therefore portable. An example document centred environment for computer-aided control system design (CACSD), that integrates MATLAB and SIMULINK with the document-based framework, is briefly described and indications for future possibilities for this technology are given.

control structure comparison for three-product Petlyuk column

Chinese Journal of Chemical Engineering 2018年第8期26卷 1621-1630页

The focus of this paper is to investigate different control structures(single-loop PI control) for a dividing wall(Petlyuk) column for separating ethanol, n-propanol and n-butanol. Four control structures are studied. All the results are simulations based on Aspen Plus. control structure 1(CS1) is stabilizing control structure with only temperature controllers. CS2, CS3 and CS4, containing also composition controllers, are introduced to reduce the steady state composition deviations. CS2 adds a distillate composition controller(CCDB) on top of CS1. CS3 is much more complicated with three temperature-composition cascade controllers and in addition a selector to the reboiler duty to control the maximum controller output of light impurity composition control in side stream and bottom impurity control in the prefractionator. CS4 adds another high selector to control the light impurity in the sidestream. Surprisingly, when considering the dynamic and even steady state performance of the proposed control structures, CS1 proves to be the best control structure to handle feed disturbances inserted into the three-product Petlyuk column.

Interactive control system design

引用

control ENGINEERING PRACTICE 2006年第2期14卷 177-184页

作者： Keller, JP Univ Appl Sci Inst Automat CH-4600 Olten Switzerland

This contribution describes a LabVIEW-based interactive computer-aided control system design tool. Although it does not provide the flexibility of common low-level design tools, it offers a set of comfortable, ready-to-use solutions for plant identification, loop-shaping or LQR/LQG-controller design and controller implementation. The tool integrates into industrial plant control and enables engineers to efficiently do the control system design from plant identification to controller implementation on the same platform. The user interface with convenient system editors and analysis tools facilitates the user to interactively attain the design goals. If desired, a configurable wizard leads the user through the design process. (c) 2005 Elsevier Ltd. All rights reserved.

A structured methodology for the design and implementation of control and supervision systems for robotic applications

IEEE TRANSACTIONS ON control systemS TECHNOLOGY 2002年第2期10卷 272-279页

作者： Ferrarini, L Carpanzano, E Politecn Milan Dept Elect & Comp Sci I-20133 Milan Italy

The adoption of a structured development methodology, based on a design cycle and on formal reference models, is a key issue to manage, possibly in a step-by-step fashion, the design of industrial control and supervision systems, as there are in modern robotic applications. In the present work, a development technique is illustrated, which extends some of the most relevant solutions and methods used to effectively deal with the design of complex control systems and integrates them into a structured methodology with analysis and simulation facilities. The main discriminating features of the presented framework are: the object-oriented approach, compliance with international standards for control software specification, hybrid dynamic models and automatic code generation. The development and implementation of a robot mission for a six degree-of-freedom manipulator is illustrated to highlight the benefits and advantages of the proposed methodology.

An improved Toeplitz algorithm for polynomial matrix null-space computation

引用

APPLIED MATHEMATICS AND COMPUTATION 2009年第1期207卷 256-272页

作者： Zuniga Anaya, J. C. Henrion, D. Univ Guadalajara Dept Math Guadalajara 44430 Jalisco Mexico Univ Toulouse LAAS CNRS F-31077 Toulouse France Czech Tech Univ Fac Elect Engn Prague Czech Republic

In this paper, we present an improved algorithm to compute the minimal null-space basis of polynomial matrices, a problem which has many applications in control and systems theory. This algorithm takes advantage of the block Toeplitz structure of the Sylvester matrix associated with the polynomial matrix. The analysis of algorithmic complexity and numerical stability shows that the algorithm is reliable and can be considered as an efficient alternative to the well-known pencil (state-space) algorithms found in the literature.

Flexcontrol is presented in this paper as a CAE (computer-aided-Engineering) platform for designing real-time fuzzy control systems: Capable of integrating all the four phases for the design, namely, tuning, simulation, prototyping and field testing, Flexcontrol allows the whole design process to be cycled easily and efficiently, thus considerably speeding up the control system design and prototyping. Its hardware architecture and software development are detailed. Its usage is described, along with two illustrative examples.
