ABSTRACT

Dynamic matrix control (DMC) is a method suitable for the control “of processes.” The method was developed by control professionals in the oil industry in the 1970s. The method provides a continuous projection of a system’s future output for the time horizon required for the system to reach a steady state. The projected outputs are based on all past changes in the measured input variables. A key tool of the DMC is the dynamic matrix which can be constructed from a process’ unit-step response data. The additional results obtained have further revealed the capability of the method and its comparison to other control methods. A demerit of DMC is that it is limited to open-loop bounded-input–bounded-output stable type of processes. C. R. Cutler gives a very lucid description of the concept. The method is based on the step response characteristics of a process, and therefore, is a time domain technique.
