Lyapunov Function for Periodic Economic Optimizing Model Predictive Control
Paper in proceedings, 2013
Model Predictive Control (MPC) schemes are commonly using reference-tracking cost functions, which have attractive properties in terms of stability and numerical implementation. However, many control applications have clear economic objectives that can be used directly as the NMPC cost function. Such NMPC schemes are labelled Economic NMPC. Unfortunately, Economic NMPC schemes suffer from some drawbacks. In particular, stability results for economic NMPC are still very sparse. A Lyapunov function for Economic NMPC was first proposed in  for problems having a steady-state optimum. The present paper develops a further generalization and clarification of these results for periodic systems.
