“…Therefore, an exceedingly fast transient response is required for a current regulator, however, the approach in Equation ( 18) risks decreasing the dynamic performance of current control. Thus, as described previously, variable smoothing is introduced in this study, whereby the parameter K α in Equation ( 18) is determined at every control step, to achieve both fast transient response and effective current ripple suppression [31].…”

“…In particular, the regulator for current control requires a much faster transient response than speed or angular position control do, as the latter include the slower mechanical dynamics in the control system. Therefore, in the proposed strategy, a variable smoothing process first introduced in [31] is applied at the generation stage for the smoothed voltage candidates, allowing stronger smoothing for producing voltage candidates in steady state. Doing so ensures a good transient response while reducing the current ripple.…”

Finite control set model predictive control (FCS–MPC) has been deployed extensively in electric motor drives and power electronics applications. Many advantages, including fast transient response, have been reported. However, the improvement of its steady‐state performance, that is, suppression of current ripple, is one of the main problems of a conventional FCS–MPC strategy. This article presents a current control strategy based on FCS–MPC using the concept of variable voltage smoothing. In the proposed method, a finite set of novel voltage vectors, produced by the smoothing process, are introduced as candidate control input candidates, and the controller generates the optimum output voltage using a modulator integrated with the FCS–MPC scheme. Thus, the voltage candidates are generated flexibly, and a suitable voltage for acceptable steady‐state performance is determined as the control input. In addition, the smoothness in the proposed concept can be updated automatically depending on the drive situation, that is, transient, or steady‐state operation, thus avoiding degradation of dynamic performance. Simulation and experimental results obtained with a permanent magnet synchronous motor drive system demonstrate that the proposed control strategy is effective to achieve current control with fast tracking performance while suppressing current ripple.
