Abstract

Based on the discrete time mixed logical dynamical (MLD) model of hybrid system, mixed integer predictive control of hybrid system with inputs constraint is studied in this paper and the optimal control problem is cast as a standard mixed integer quadratic programming (MIQP) problem. In order to reduce online computational burden of the optimal control problem, and at the same time, to maintain good control performance and as largest as possible feasible region, a mixed integer model predictive control strategy with dynamic control horizon is purposed. At the end of the paper, simulations for a vibration control of elevator´s mechanical system are made
