Solid oxide fuel cells (SOFCs) are considered the most important in the field of fuel cells. However, SOFCs give a challenging control problem due to their slow dynamics, complex non-linearity, and operating constraints. In this study, an improved model free adaptive constrained control scheme is proposed to solve the SOFC control problem with I/O measurement data. Since the control terms appear within the unknown non-linear dynamic, an improved compact form dynamic linearisation data driven modelling method is used to simplify the SOFC system. In the design procedure of the controller, a novel dynamic anti-windup compensator is used to deal with the move magnitude and rate saturations of SOFC control input. Moreover, the authors also theoretically prove that all the signals in the closed-loop system are uniformly ultimately bounded based on Lyapunov stability analysis method. Finally, simulation results are given to demonstrate the effectiveness and potential of the proposed constrained control scheme.
