Application of the immune system reaction mechanism concept to sequential control

Abstract

The paper demonstrates the application of the immune system reaction concept to sequential control by determining control sequences of sequential control plants modeled by PI*-nets, a sub-class of Petri nets with modular modeling characteristics. We propose an approach for finding control sequences based on the immune system response mechanism, where the problem is formulated as a firing sequence problem. The original problem is divided into several smaller sub-problems, the model itself is divided into several sub-models and local firing sequences that will compose the original model firing sequence are selected by interacting common transitions of these sub-models through local objective functions. Local objective functions are set dynamically by internal and inter sub-problem interactions based on the immune system response regulatory model. Simulations demonstrated the validity and promising performance of the proposed approach.
