A two-layer LPV based control strategy for input and state constrained problem: Application to energy management

This paper proposes a pragmatic solution to solve input and state constrained control problems. Taking benefits from a two-layer hierarchical architecture, in particular by working at a different period at each level, the general idea is to combine an explicit LPV controller ensuring the regulation task, and a predictive control at the upper level to comply with the active constraints. In practice, the two layers are connected as the external loop drives the varying parameter of the inner loop. The proposed scheme is well suited mainly with control problems whose constraints violation risks may be predicted sufficiently in advance. The energy management of a hybrid vehicle is finally considered to illustrate the applicability.
