摘要：AbstractThis paper deals with a predictive disturbance compensator for processes characterized by input-output and disturbance-output time delays. The proposed scheme provides a solution for configurations where the application of classical feedforward approach results in poor performance. The analyzed technique merges the advantages of classical feedforward control scheme, which can be combined with any feedback controller, and the use of future disturbance estimation in the predictive control mechanism. The predictive compensator is based on the GPC (Generalized Predictive Control) algorithm exploiting its prediction capabilities. The evaluation of the proposed disturbance rejection scheme is performed through simulation and compared to common techniques in order to highlight the advantages and drawbacks. The obtained results show that the proposed approach can significantly improve the disturbance attenuation in process control tasks.
