A deadbeat or digital predictive controller has very good dynamic and steady state performance, but satisfactory control results heavily depend on the accuracy of the model and parameters used. To compensate the system uncertainties, a novel current regulation method, a deadbeat fuzzy algorithm, is presented in this paper. The regulator consists of a deadbeat loop and a fuzzy compensation loop. The deadbeat loop generates the major part of the command voltage based on the nominal system conditions, which guarantees the system a very quick dynamic response. The fuzzy compensation loop generates an additional part of the command voltage in case any difference between command and actual currents occurs, which minimizes the effects of system uncertainties. As all the variables are processed in the stationary reference frame, the algorithm is simple to be implemented. Simulation and experimental results from a 5 hp induction machine system are presented to verify the effectiveness of the proposed deadbeat fuzzy current regulation algorithm.
