Interval-Based Sliding Mode Control for High-Temperature Fuel Cells Under Actuator Constraints

Interval-based sliding mode controllers can be used efficiently for a robust stabilization of systems with bounded uncertainty. The real-time implementation of these procedures makes use of software libraries that provide functionalities for interval analysis and algorithmic differentiation. This paper gives an overview of possible extensions of such control procedures for the reliable stabilization of the thermal behavior of high-temperature solid oxide fuel cell systems. During the real-time stabilization, limitations of the range of state and control variables are treated by constraints implemented in a barrier Lyapunov function approach.
