In this article, an optimized sampling mechanism for full-state feedback current control (FSFCC) of $LCL$ -equipped high-speed permanent magnet synchronous motor drives is proposed. First, the full-state current control structure is introduced and it indicates that the control performance suffers from the sampling harmonic components caused by the pulsewidth modulation. Then the sampled capacitor voltage and the inverter current are analyzed theoretically with different sampling trigger times. Based on the harmonic analysis, an optimized sampling mechanism is developed and the current ripple is much reduced compared with the conventional method. Finally, the effectiveness of the proposed method is validated by the experimental results at 100 kr/min.
