Transient Reduction in Reconfigurable Control Systems Utilizing Structure Dependence Supervisory 4 sub - system 4

Reconfigurable Abstract Reconfigurable control systems are promising alternatives to efpciently control complex time-variant andlor non-linear systems, such as vehicles, gas turbines, etc., which might require a certain level of faultoperational behavior, as well. Reconfigurable control systems are designed to be able to change the controller at run-time to react to failures, compensate the time-variant andlor nonlinear nature of plant, or accommodate changes in the control objectives. However, these changes in the plant andlor in the controller may cause intolerable transient. Management of these reconfiguration transients is an open issue. The dependence on the structure of the plant and the controller is identified as a key factor determining the reconfiguration transients. In this paper, some of the possibilities of reducing these transients are investigated. The results are demonstrated on a plant with two modes (operational and failure) controlled by properly designed PID controllers. #
