ABSTRACT
Dynamic Matrix Control (DMC) has many similarities with Model Algorithmic Control (MAC). It is an algorithm based on the step response model. Having an impulse response model is equivalent to having a step response model. However, DMC applies incremental algorithms, which is very effective in removing the steady-state error. Certainly, compared with DMC, MAC has its advantages, such as higher disturbance rejection capacity. In real applications, choosing between DMC and MAC depends on the precise situation. DMC is the most widely accepted in the process industry. The constraints in (v) are usually hard constraints. Before DMC is implemented and in the real application of DMC, users can tune the following parameters: In general, it does not need to often tune the modeling coefficients of the step response model; the main reason is the same as that for the impulse response model.
