Abstract
There are many advanced control techniques developed over last years. Only few of them found their way to industrial implementation. The paper presents Predictive Functional Controller (PFC), which has many implementations, however is rarely presented in publications. That type of control is used as a standard PID control replacement to meet higher quality demands of controller performance. The paper presents example of implementation of PFC in Allen-Bradley Control-Logix platform. Complexity of considered problems includes non-linearity, constrains, feedforward action, integrative effect. The paper generic control scheme was designed to facilitate industrial implementation where tuning is very simple and only concerns one parameter. That simplicity of tuning makes model-based predictive control accessible to non-experts. Results of PFC controller are compared to the results of standard PI controller used for the same process.
