Dynamic Matrix Control Tutorial Dynamic Matrix Control (DMC) was the first Model Predictive Control (MPC) algorithm introduced in early 1980s. Nowadays, DMC is available in almost all commercial industrial distributed control systems and process simulation software packages. This tutorial intends to explain the features of DMC using the dmc function developed by the author.
