Control of integrating processes using dynamic matrix control
Dynamic Matrix Control (DMC) has been popular for the control of chemical and petroleum processes. These processes commonly include integrating process units, which produce a ramp change in the output for a step change in input. When DMC is used for control of integrating process units, a steady-state offset occurs for sustained load changes. This offset is not acceptable for certain applications. A simple modification in the DMC algorithm that eliminates this offset is presented in this paper. The performance of the proposed algorithm is presented on SISO and MIMO example problems through simulations and experimental results.
