QDMC is a set of Fortran programs for constrained Quadratic Dynamic Matrix Control Simulation and property study of the QDMC "equivalent" feedback linear controllers. Based on the time invariant impulse response model and plant, the simulation program minimizes a quadratic objective function subject to hard constraints on manipulated variables and/or on controlled variables. On-line stability conditions are also calculated in this program.

There are five programs created for studying the properties of the controller. Program CJI creates QDMC "equivalent" feedback linear controllers as frequency files which depend on the active constraints situation. Program CJINOM is for nominal stability test of these controllers. Program CJISEP is used to separate them into tuning parameter dependent and independent sets. Program PREL is for testing the practical relevance of a set of QDMC active constraints. Program ALLPREL finds all such practically relevant sets.
