On the intricacies in the dynamic regulatory control of chaotic systems

Abstract

Issues related to the dynamic regulatory control of a chaotic process are discussed and illustrated using phenomenological descriptions of nonlinear systems from different disciplines. The controller design is based on internal model control principles with a capability of handling constant load and stochastic disturbances. Simulation studies assess the control performance and the studies reveal the intricate stability features of chaotic dynamics which need to be considered for regulatory control. The studies also suggest that a proper choice of the controller variable, leading to a suitable range in the values for the controller output, may be required.
