Abstract :
An improved synthesis approach of the dynamic output feedback model predictive control, which has a near-optimal solution, for the polytopic uncertainty system with bounded disturbance, is given. This paper takes advantage of the method in (Automatica (2008) pp. 258-264) to re-handle the physical constraints. Hence, there are more scalar slack variables for optimization, so that the control performance can be improved. This represents a general formulation which includes a previous work as a special case. A numerical example is given to show the effectiveness of the controller.
