  • pid Control System Analysis and design
    IEEE Control Systems Magazine, 2006
    Co-Authors: Yun Li, G Chong
    Abstract:

    With its three-term functionality offering treatment of both transient and steady-state responses, proportional-integral-derivative (PID) Control provides a generic and efficient solution to real-world Control problems. The wide application of PID Control has stimulated and sustained research and development to "get the best out of PID", and "the search is on to find the next key technology or methodology for PID tuning". This article presents remedies for problems involving the integral and derivative terms. PID design objectives, methods, and future directions are discussed. Subsequently, a computerized simulation-based approach is presented, together with illustrative design results for first-order, higher order, and nonlinear plants. Finally, we discuss differences between academic research and industrial practice, so as to motivate new research directions in PID Control.

  • pid Control System Analysis design and technology
    IEEE Transactions on Control Systems and Technology, 2005
    Co-Authors: Kiam Heong Ang, G Chong
    Abstract:

    Designing and tuning a proportional-integral-derivative (PID) Controller appears to be conceptually intuitive, but can be hard in practice, if multiple (and often conflicting) objectives such as short transient and high stability are to be achieved. Usually, initial designs obtained by all means need to be adjusted repeatedly through computer simulations until the closed-loop System performs or compromises as desired. This stimulates the development of "intelligent" tools that can assist engineers to achieve the best overall PID Control for the entire operating envelope. This development has further led to the incorporation of some advanced tuning algorithms into PID hardware modules. Corresponding to these developments, this paper presents a modern overview of functionalities and tuning methods in patents, software packages and commercial hardware modules. It is seen that many PID variants have been developed in order to improve transient performance, but standardising and modularising PID Control are desired, although challenging. The inclusion of System identification and "intelligent" techniques in software based PID Systems helps automate the entire design and tuning process to a useful degree. This should also assist future development of "plug-and-play" PID Controllers that are widely applicable and can be set up easily and operate optimally for enhanced productivity, improved quality and reduced maintenance requirements.

  • Robust Control System Analysis and synthesis
    International Conference on Control '94, 1994
    Co-Authors: Neil Munro
    Abstract:

    This paper considers two topics in the area of robust Control System Analysis and synthesis. The first topic is concerned with the testing for zero inclusion of 2-D convex polytopes, which is essential in the robustness Analysis of linear Systems based on generalisations of Kharitonov's four-polynomial concept. Barmish (1989) has extended the Kharitonov approach to the more general case of polynomials subject to linearly dependent coefficient perturbations and more general zero location regions, but this is accompanied by various computational problems. These are analysed and two new more direct and computationally less intensive approaches, which produce much more accurate results, are presented. The second topic is concerned with a modification to existing dyadic and full-rank pole assignment design methods for MIMO uncertain Systems having affine linear perturbation structures, in which a gain factor is introduced in order to ensure robustness stability and performance. An illustrative example is also included.

  • Control System Analysis and design using Mathematica
    Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 1
    Co-Authors: Neil Munro
    Abstract:

    This paper discusses recent experiences using polynomial methods to solve an industrial Control problem. The System concerned is a gasifier unit used in integrated gasification combined cycle electrical power plants. Several new extensions to Mathematica's Control System Professional package were used to determine a good Control scheme for the gasifier.

  • Teaching modern Control System design
    Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 1999
    Co-Authors: R.h. Bishop, Richard C Dorf
    Abstract:

    The Control System Analysis and design approach adopted by R.C. Dorf and R.H. Bishop (1998) and its companion text by R.H. Bishop (1997) is discussed. One important goal is to provide students with an introduction to the process of Control System design. A series of steps embodied in a block diagram guides the students through the Control System design process. Two examples are presented to highlight the use of the design process block diagram.

  • A Set of Minitools for Education in Control System Analysis and Design
    European Journal of Engineering Education, 1993
    Co-Authors: P. Kolb, M. Rickli, W. Schaufelberger
    Abstract:

    Abstract Summary Minitools are software tools that have been especially designed and implemented for use in education and on small industrial problems. They offer limited capabilities if compared to full-grown commercial Systems but are much easier to learn and to use. Three such programs are introduced in this paper: DESolver for differential equation solving; Frequency for frequency response Analysis and design; and BDE Sim for simulation and frequency response Analysis from block diagrams. BlockSim, which is more a tool for implementation than a minitool, is also presented briefly. The four programs run on Macintosh and IBM compatible PCs. All programs are in the public domain; on the IBM PC a GEM desktop is needed to run them.

  • Minitools for Education in Control System Analysis and Design
    IFAC Proceedings Volumes, 1991
    Co-Authors: P. Kessler, W. Schaufelberger
    Abstract:

    Abstract Minitools are software tools that have been especially designed and implemented for use in education and on small industrial problems. They offer limited capabilities if compared to full grown commercial Systems but are much easier to learn and to use. Four such programs are introduced in the paper: Abakus, a program for function graphing; DESolver for differential equation solving; Frequency for frequency response Analysis and design, and BDE Sim for simulation and frequency response Analysis from block diagrams. The four programs run currently on Macintosh and IBM compatible PC's and are being ported to the Atari. All programs are in the public domain; on the IBM PC a GEM desktop is needed to run them.
