CURRENT RESEARCH INTERESTS
Discrete-event control and software synthesis: This research focuses on the development
of efficient techniques to automatically convert high-level control
specifications into discrete event control laws for manufacturing systems and
embedded controllers. Current
research emphasizes application to manufacturing systems and low-level
controllers (embedded controllers), with issues such as state targeting,
coordination timing, and automatic generation of computer code.
Embedded Systems for Sensing and Control in Food
Processing Industries: This
research involves the design of embedded systems for analysis of sensor
information in food processing industries.
The goal is the development of a generic platform capable of being
rapidly reconfigured for a variety of sensing methods and signal analysis
algorithms.
Automated fault monitoring of
manufacturing systems. This research considers the problem of
fault monitoring of manufacturing systems using signals from discrete sensors
and actuators. The emphasis is on distributed monitoring of processes with
concurrent event sequences by using timing and sequencing characteristics of
I/O signals. Related work considers
automated learning of the timing characteristics, as well as systems with
underlying continuous dynamics, infrequent continuous-valued sensing, and
various forms of restricted concurrency.
Active sensing policies for
uncertain systems. This research activity considers the
problem of systems where sensing occurs only upon request, but each sensing
carries a cost. The issue is to
develop a sensing policy such that the control or sensing objectives can be met
at minimum cost, while guaranteeing to constrain the state uncertainty under
several different uncertainty measures.
