  • Control System Design Automation for Mechanical Systems
    Journal of Intelligent and Robotic Systems, 1998
    Co-Authors: Kiyoshi Maekawa, Grantham K. H. Pang
    Abstract:

    In this paper, a user-friendly and comprehensive control system Design Package called Control System Design Automation (CSDA) is described. The system consists of five main blocks: a requirement interpretation block, a modeling block, an analysis/Design block, a database management and knowledge base block, and a verification block. The requirement interpretation block transforms the specifications in terms of the application to those in terms of control. The analysis/Design block selects an optimal control structure and determines the controller parameters. In addition to the conventional Design methods, CSDA also contains the more recent Design methods such as the LMI Design approach and the Kessler/Manabe method. The LMI approach can obtain a controller which satisfies multiple specification items at the same time. The configuration of the system as well as the analysis/Design block are described in detail in this paper.

  • Systematic Procedures for the H/spl infin/ Controller Design of a Single Flexible Link
    Proceedings. The First IEEE Regional Conference on Aerospace Control Systems, 1993
    Co-Authors: T. Ravichandran, Grantham K. H. Pang
    Abstract:

    In this paper, we present systematic procedures for the controller Design of a single flexible link using the H/spl infin/ optimization method. Our approach provides a coupling of the Design knowledge and Design algorithms for carrying out the controller Design. Design knowledge of the systematic procedures involved has been represented in the knowledge-based development environment of the MEDAL control system Design Package. The algorithmic procedures for numeric processing are represented as user-defined functions (M-files) in the same control system Design Package. Hence, MEDAL provides a novel Design environment which enables both heuristic and algorithmic knowledge to be integrated for H/spl infin/ control system Design.

  • A knowledge environment form an interactive control system Design Package
    Automatica, 1992
    Co-Authors: Grantham K. H. Pang
    Abstract:

    Abstract This paper describes a generic expert system development environment in a computer-aided control system Package called SFPACK. The basic command language of the Package follows the well-known MATLAB syntax. However, SFPACK has evolved from the MATLAB-derived control environment to a new generation of control system Design environment because of the novel knowledge environment developed within the Package. SFPACK now supports a richer set of data structures for representing Design objects and knowledge in the control environment. In this paper, the features of the knowledge environment is presented. The issue on coupling of symbolic and numeric processing is also discussed. An expert system for control system Design is developed in this integrated environment.

  • Knowledge-Based Interfaces to a Computer-aided Control System Design Package
    IFAC Proceedings Volumes, 1991
    Co-Authors: Grantham K. H. Pang
    Abstract:

    Abstract Design of automatic control systems is a computationally intensive process. This motivates the development of accessible, easily usable and shareable interactive computing environment incorporating specialized knowledge of the theory and codified practice of automatic control. Expert and knowledge based systems play key role in creation of such environment. The expert system techniques can be used for the Design of control systems. SFPACK is a special purpose interactive computer language for control system Design. One feature of this Package is that it incorporates an expert system development facility called DECESS. This expert system development facility can be used to Design controllers for linear multivariable control systems. This paper describes an object-oriented knowledge interface to SFPACK. SFPACK has been used as a teachware for presenting techniques in control system Design. The Package runs on a SUN workstation or VAX machines and has been used successfully in a course on control engineering at the graduate level.

  • Expert system for SROOT
    IEE Proceedings, 1991
    Co-Authors: P A Muha
    Abstract:

    The development of an expert system in the domain of computer-aided control systems Design is presented. An expert system has been developed and incorporated into an existing control systems Design Package called SROOT. The combined software is used to Design linear single variable systems using the root locus tech-niques. The expert system provides software-based Design expertise involving control theory, visual aspects of graphical outputs and engineering heu-ristics. Two new components for the expert system are introduced. These are the two types of facts used and a firing order unit. The former enables rules to be written in a generally-applicable format. The latter provides a systematic way of applying expertise. An overall Design heuristic which supports the Design of leadbag com-pensators for the systems considered is introduced. A Design example is given to exhibit the capability of the expert system.

  • Solar heating system final Design Package
    2013
    Co-Authors: Nasa
    Abstract:

    The system is composed of a warm air collector, a logic control unit and a universal switching and transport unit. The collector was originally conceived and Designed as an integrated roof/wall system and therefore provides a dual function in the structure. The collector serves both as a solar energy conversion system and as a structural weather resistant skin. The control unit provides totally automatic control over the operation of the system. It receives input data from sensor probes in collectors, storage and living space. The logic was Designed so as to make maximum use of solar energy and minimize use of conventional energy. The transport and switching unit is a high-efficiency air-handling system equipped with gear motor valves that respond to outputs from the control system. The fan unit was Designed for maximum durability and efficiency in operation, and has permanently lubricated ball bearings and excellent air-handling efficiency.

  • Computer aided Design Package for true digital control (TDC) systems
    1991
    Co-Authors: Wlodek Tych, Arun Chotai, Peter C. Young
    Abstract:

    The paper outlines briefly the theoretical background to the TDC Design procedure, which is based on new methods of input-output state variable feedback control which exploit a non-minimum state space formulation of the control problem using either pole-assignment or linear quadratic optimal control strategies. It then goes on to describe the main features of the computer aided control system Design Package, which provides the user with assistance at all stages in the Design process; from model identification and estimation to final control system Design and evaluation, including a rather novel use of Monte Carlo analysis to assess the potential effects of model uncertainty on the closed loop system behaviour.
