Synthesis of Robust Constrained Inventory Control in Supply Networks on the Base of Descriptor System Approach
RESUMO
The problem of robust constrained inventory control synthesis in supply networks under action of unknown, but bounded external demand, is solved. The control law is constructed in the form of a linear dynamic feedback with respect to discrepancy signals between the available and reserve stock levels of resources. In order to suppress the influence of external disturbances, modeling the changes of demand, at the same time ensuring robust stability of the closed-loop system, the method of invariant ellipsoids is applied, using descriptor system and parameterized Lyapunov function. Using the linear matrix inequalities technique the control synthesis problem is reduced to a sequence of semidefinite programming problems.
