Min-max model predictive control for constrained nonlinear systems via multiple LPV embeddings

Science in China(Series F) 2009年第7期52卷 1129-1135页

A min-max model predictive control strategy is proposed for a class of constrained nonlinear system whose trajectories can be embedded within those of a bank of linear parameter varying （LPV） models. The embedding LPV models can yield much better approximation of the nonlinear system dynamics than a single LTV model. For each LPV model, a parameter-dependent Lyapunov function is introduced to obtain poly-quadratically stable control law and to guarantee the feasibility and stability of the origi- nal nonlinear system. This approach can greatly reduce computational burden in traditional nonlinear predictive control strategy. Finally a simulation example illustrating the strategy is presented.

＜正＞ This work studies the issue of optimal output transition control for nonlinear flat differential systems with constraints. Of special interest here is to generate a state reference trajectory and a feedforward input command, which are essential for the implementation of exact feedforward linearization. Our approach is to transfer the transition problem in the real output space into a trajectory planning issue in the flat output space. The new aspect of this idea in our approach is to involve the generation of a noncausal trajectory for the flat output. This novelty turns out to be considerably effective for the performance improvement. It is also remarkable that our methodology guarantees the planned trajectories feasible for all nonlocal transitions. This is a new contribution to noncausal output transition control of nonlinear systems. The proposed method is illustrated on a benchmark system, the ICSTR, although its applicability could be much more wider.

＜正＞We present in this paper a quasi-infinite horizon model predictive control scheme for stable and unstable nonlinear systems subject to input and state constraints. Hard state constraints are relaxed in an optimal way to avoid infeasibility. With an additional terminal cost in the standard finite horizon objective function and a terminal inequality constraint, the control profile to be determined by on-line optimization is only of finite horizon. The feasibility of the terminal inequality constraint implies that the states at the end of the finite horizon are in a terminal region. The terminal cost bounds the infinite horizon cost of the nonlinear plant model controlled by a local linear state feedback, if the terminal region satisfies some reasonable conditions. The closedloop stability is guaranteed by the feasibility of the optimization problem at the very beginning.
