Title: Device Oriented Project Controller

Abstract

This proposal is directed at the issue of developing control systems for very large HEP projects. A de-facto standard in accelerator control is the Experimental Physics and Industrial Control System (EPICS), which has been applied successfully to many physics projects. EPICS is a channel based system that requires that each channel of each device be configured and controlled. In Phase I, the feasibility of a device oriented extension to the distributed channel database was demonstrated by prototyping a device aware version of an EPICS I/O controller that functions with the current version of the channel access communication protocol. Extensions have been made to the grammar to define the database. Only a multi-stage position controller with limit switches was developed in the demonstration, but the grammar should support a full range of functional record types. In phase II, a full set of record types will be developed to support all existing record types, a set of process control functions for closed loop control, and support for experimental beam line control. A tool to configure these records will be developed. A communication protocol will be developed or extensions will be made to Channel Access to support introspection of components of a device.more » Performance bench marks will be made on both communication protocol and the database. After these records and performance tests are under way, a second of the grammar will be undertaken.« less

  • A methodology for reducing the complexity of designing dedicated real-time control systems is developed. It is shown that three areas are amenable to automation: the selection and configuration of hardware, the production of software, and the adaptation of a monitor to maintain real-time integrity of the entire system. The concept of hardware binding is introduced, and it is shown that delaying the point in the design cycle where hardware is functionally bound allows a new approach to machine independence. Concepts which allow expression of repetitive control situations are described, and a realization-independent language (CSDL), based on these concepts, is defined.more » Methods for automatically selecting a time-wise correct monitor are classified, and techniques for specifying the realization capabilities of digital processors are discussed. These concepts and techniques are brought together in a design automation system for the production of a complete controller design from a behavioral description. An example description is traced through the CSD System; a software listing and hardware configuration document for an actual microprocessor (the Intel 8080) is produced. This research provides a structured description of the control system design process, and allows a unified perspective in the realization of controllers for applications previously considered to be unrelated. The concepts developed define a new direction in the production of real-time control systems. 9 figures, 4 tables.« less
  • One of the most effective ways to enhance boiler efficiency is to improve the steam generation control system. This provides motivation for the development of a control oriented boiler model which can be used for the synthesis of the model-based control algorithms as well as testing of new boiler control systems on a real-time simulator based on the model. This report presents a fairly accurate boiler model developed on the basis of fundamental physical laws, previous efforts in boiler modeling, known physical constants, plant data, and heuristic adjustments. The model is nonlinear, fourth order, and includes inverse response (shrink andmore » swell effects), time delays, measurement noise models, and a load disturbance component.« less
  • We describe the ARC effort leading towards the computer oriented multichannel DC-SQUID system. More specifically, we describe the prototype of lock-in, bipolar preamplifier and flux counter implemented by our team. The results of tests are quoted and show that our CD-SQUID electronics compare favorably with both commercially available BTI-Dynabias and Berkeley readout electronics. More specifically, our system seems to be more user friendly and easier to interface to the computer.
  • A sensor-based intelligent control system is described that utilizes a multiple degree-of-freedom robotic system for the automated remote manipulation and precision docking of large payloads such as waste canisters. Computer vision and ultrasonic proximity sensing are used to control the automated precision docking of a large object with a passive target cavity. Real-time sensor processing and model-based analysis are used to control payload position to a precision of {plus_minus} 0.5 millimeter.
