Use of Anti-Windup Techniques for Control of Solid Oxide Fuel Cells 2016-32-0016
This papers aims at using anti-windup augmentation to an existing high performance controller to increase the range of net-power that can be obtained from a solid oxide fuel cell. The power drawn by the fan/blower is kept limited by a software/controller enforced bound that acts similar to a saturation bound. Anti-windup augmentation is then used to ensure stability and recovery of performance. The be-havior of the controller, particularly the effects of the anti-windup loops on the second actuator (cathode inlet temperature), is then investigated to evaluate the feasibility of the proposed approach.
