DMC (Dynamic Matrix Control)

DMC (Dynamic Matrix Control) mentioned in this article is a predictive control algorithm. The algorithm achieves system control through simulation using a first-order model. A key implementation aspect involves constructing a dynamic matrix from the system's step response coefficients, which forms the basis for predicting future system behavior. The main advantages of the DMC algorithm include its ability to provide rapid system response and excellent robustness against system disturbances. Additionally, the DMC algorithm can minimize control errors while maximizing system performance metrics through quadratic programming optimization, thereby achieving superior system control performance. The control law calculation typically involves solving an optimization problem that considers both control increments and output predictions over a predefined horizon. Consequently, the DMC algorithm finds widespread application across numerous control domains, particularly in process industries where its predictive capabilities offer significant advantages.
