A novel hierarchical control architecture for a class of discrete-event systems

Robust Model Predictive Control for a Class of Discrete Nonlinear systems

This paper presents a robust model predictive control scheme for a class of discrete-time nonlinear systems subject to state and input constraints. Each subsystem is composed of a nominal LTI part and an additive uncertain non-linear time-varying function which satisfies a quadratic constraint. Using the dual-mode MPC stability theory, a sufficient condition is constructed for synthesizing the ...

A new hierarchical control scheme for a class of cyclically repeated discrete-event systems

We extend the hierarchical control method in (Li et al., 2004) to a more generic setting which involves cyclically repeated processes. A hierarchical architecture is presented to facilitate control synthesis. Specifically, a conservative max-plus model for cyclically repeated processes is introduced on the upper level which provides an optimal online plan list. An enhanced min-plus algebra base...

A hierarchical control structure for a class of timed discrete event systems

A Hierarchical Architecture for Nonblocking Control of Decentralized Discrete Event Systems

This contribution investigates the hierarchical control of decentralized DES which are synchronized by shared events. A multi-level hierarchical control architecture providing hierarchical consistency is introduced. Moreover, it allows for composition of decentralized subsystems on the high-level of the hierarchy, and hence reduces the computational complexity of supervisory control synthesis f...

Hierarchical control of discrete-event systems

This paper is an overview of the current research on hierarchical control of discrete-event systems. Four major approaches are identified and described: bottom-up design, top-down design, state aggregation, and interface-based design. The research examined is grouped into these sections, in an attempt to unify the terminology and concepts where possible without an in-depth theoretical investiga...
