N2 - This paper presents a load change assessment-based feedforward compensation method for finite control set model predictive current control (FCS-MPCC) in permanent magnet synchronous motors (PMSMs). The objective is to address the adverse effects of load disturbances on FCS-MPCC, which can lead to deteriorated control performance and system instability. To mitigate these effects, a novel feedforward compensation mechanism is proposed by integrating a load change assessment mechanism within the FCS-MPCC framework. The mechanism enables real-time estimation of load changes by accurately capturing their rate and direction. A sliding mode torque observer (SMTO) is developed to ensure accurate load estimation, characterized by fast response and strong robustness. The stability of the SMTO is analyzed using a Lyapunov function. Furthermore, a technique is proposed to generate feedforward compensation values based on the load change assessment, specifically applied to the q-axis reference current. Comparative simulation results verify the effectiveness of the proposed strategies.
