    Computer-aided control engineering (CACE) environments, in order to be reusable in a broad spectrum of applications, have to be based on an open software framework that provides seven classes of services: database services; model-definition services; algorithmic services; tool-control services; task-control services; user-interaction services; and process-communication services. This is detailed h... View full abstract»

    Increasingly, design engineers are identifying new opportunities for innovation by incorporating active microprocessor control into mechanical systems of all types; e.g., spacecraft and aircraft, ground vehicles, robots, and machine tools. These mechanical systems are often complex, multibody dynamical systems with rigid and elastic substructures. Their behavior is often inherently nonlinear over ... View full abstract»

    Current computer-aided control system design environments seldom support optimization methods for controller design in a truly interactive manner. A prototype tool, called PARSIM, supporting parallel processing, optimization, and a graphical user interface is presented, addressing many of the problems inherent in current approaches to multiobjective optimization-based design methods. An XWindows i... View full abstract»

    This article describes software developed in SIMULINK that enables the behavior of feedback control systems with actuator saturation and PID controllers to be evaluated. The software, which is part command- and part menu-driven, allows a choice of four PID controllers using different integral wind-up strategies and transfer function entry of the actuator and plant dynamics. Most realistic control ... View full abstract»

  • A separation principle for hybrid control system design

    Publication Year: 1995, Page(s):80 - 84
    Cited by:  Papers (9)

    Presented here is a method, based on automatic control system design practice, for the synthesis of hybrid control systems, controllers that contain both real-time feedback loops and logical decision-making components. In the proposed framework, the overall design task is separated into three component parts: (1) design of the real-time control loops, (2) synthesis of the decision-making logic, an...

  • A transfer function computational algorithm for linear control systems

    The problem of computing the closed loop transfer function of a linear system represented by its block diagram or by its flow graph is of importance in CAD programs designed for the analysis of linear systems. Mason's rule (1953) is one of the available techniques to perform such calculations, but it requires searching into the graph for different paths and loops and becomes slow as system complex...

    In this article we provide a tutorial-style overview of ideas for a new computer-aided control engineering (CACE) environment. We discuss these ideas through repetition of two themes. The first theme is that the CACE environments should support a thread from requirements development to implementation. While some CACE environments come close to this today, none provides the end-to-end thread we env... View full abstract»

    In this article, we describe the language and code generator ControlH. The development of ControlH is being supported by the ARPA domain-specific software architectures (DSSA) program. The language is designed for describing guidance, navigation, and control (GN&C) algorithms in a concise yet rigorous manner. Both textual and graphical syntaxes exist. The code generator generates high-quality,... View full abstract»

    As result of a universal drive for more consistent attainment of high product quality, more efficient use of energy, and tighter safety and environmental regulations, industrial processes have evolved over the past few decades into very complex and highly integrated systems. Such stringent demands naturally create more difficult and challenging control problems for today's industrial process contr... View full abstract»

    The dawn of the electrical age brought new types of control systems. Able to transmit data between distributed components and effect action at a distance, these systems employed feedback devices as well as human beings to close control loops at every level. By the time theories of feedback and stability began to become practical for engineers in the 1930s, a tradition of remote and automatic contr... View full abstract»

    This article introduces the design environment CAMeL (Computer-Aided Mechatronic Laboratory), which supports the whole design cycle of mechatronic systems. Modern CACSD tools have to be open and easily combinable with other existing tools designated to perform special design tasks. CAMeL is a process-based development framework for control systems. Beside an internal toolset for linear analysis, n... View full abstract»
