This work discusses the performance of the predictive functional control (PFC) approach by utilizing two well-known observers as disturbance estimators for permanent magnet synchronous motors (PMSMs), which are frequently characterized by nonlinearity and uncertainty. PFC serves as a link between complicated model predictive control (MPC) and PI(D)-based control. PFC is a simplified MPC that uses prediction and can be utilized with simple software and inexpensive hardware. It should be highlighted that the traditional PFC technique does not produce good results in the presence of significant disturbances. The disturbance can be instantly rejected by compensating current through a feedforward loop. To this end, some observers were introduced. The extended state observer (ESO) and sliding-mode observer (SMO) are promising candidates among different observers. In this work, the observers assess the controlled plant s lumped disturbance, and state feedback is used to achieve appropriate control performance. Based on the simulation results, thorough comparisons are made to determine which option is preferable for the application.
