PROCESS CONTROL SYNTHESIS IMPROVED BY STRUCTURAL MODEL PROPERTIES

Hans-Christian Lapp, Hans-Michael Hanisch

Abstract

This contribution presents a novel approach to synthesize discrete process control on shop-floor level. It takes advantage of the modular composition of the used modeling formalism. The synthesis procedure grounds on the model of the uncontrolled plant behavior, as well as on specifications of forbidden states and desired process behavior. Thus, the presented approach also opens the door to more flexibility, compared to solely forbidden state specifications. The plant model structure is abstracted without loss of information into a novel representation called Transition Invariants Graph. This representation is utilized to extract admissible trajectories out of the reachable state space of the uncontrolled plant. Hence, the introduced approach reduces the complexity during control synthesis procedure significantly by limiting the reachability analysis. That makes it feasible to be used even in real-scale industrial systems.
