New matrix formulation for supervisory controller design in practical flexible manufacturing system

The paper deals with a new matrix formulation of a supervisory controller design in practical flexible manufacturing system (FMS). Design method is applied to the laboratory setup of a finite-buffer multiple re-entrant flow line FMS. Control of the FMS is based on a matrix model approach which significantly reduces the computational effort. The results obtained during experiments have confirmed that effectiveness of matrix-based FMS control in terms of deadlock-free operation is a fully feasible goal.
