Generalized Predictive Control for Constraint Hybrid System

Aiming at the properties of the object of the hybrid system, the modeling method based on the mixed logic dynamical (MLD) model has been introduced, the continuous dynamic process and the discrete dynamic process in the hybrid system are expressed into state space equations with mixed-integer inequality constraints. Through the enlargement of the classical generalized predictive control (GPC)'s object, the mixed integer quadratic programming is used to get the best GPC's control rule of the hybrid system with constraints. The simulation result shows that the GPC based on MLD model is able to stabilize the hybrid system on the desired output, and the system has better characters.
