Vista Control Systems Inc. is developing a portable system for intelligent
accelerator control. Our system is general purpose and has been designed to be
reused at multiple accelerator facilities. This portability arises from the
hierarchical object-oriented nature of the architecture. The control system
employs a multi-level organization in which knowledge based inferencing is
used to dynamically configure a variety of optimization and control
algorithms. We discuss results from recent beamline tuning tests at the
Brookhaven National Laboratory ATF and the ATLAS facility at Argonne.
Results are analyzed along a number of dimensions, including portability,
performance as benchmarked against human tuning, adaptive behavior, noise
handling, integration of control subsystems, and support for rapid knowledge
capture and utilization.
