Abstract
The design of a higher-layer controller using model predictive control (MPC) is
considered. The higher-layer controller uses MPC to determine set-points for
controllers in a lower control layer. In this paper the use of an
object-oriented model of the system for making predictions is proposed. When
employing such an object-oriented prediction model the MPC problem is a
nonlinear, non-smooth optimization problem, with an objective function that is
expensive to evaluate. Multi-start pattern search is proposed as approach to
solving this problem, since it deals effectively with the local minima and the
non-smoothness of the problem, and does not require expensive estimation of
derivatives. Experiments in an emergency voltage control problem on a 9-bus
dynamic power network show the superior performance of the proposed multi-start
pattern search approach when compared to a gradient-based approach.
