“…Existing current sampling error compensation methods can be divided into two categories. One is to estimate and compensate the current sampling errors by observers or analytical means [18][19][20]. The advantage of this kind of method is that no additional hardware is required.…”

High‐frequency (HF) square‐wave voltage injection position sensorless control method for interior permanent magnet synchronous motor (IPMSM) is widely utilised in zero and low speed range due to its good dynamic performance and easy implementation. However, this method relies on the sampling accuracy of current sensors for rotor position estimation. To overcome this restriction, an HF square‐wave voltage injection position sensorless control method for IPMSM using a single current sensor (SCS) is proposed. Firstly, the impact of current sampling errors on HF square‐wave voltage injection position sensorless control is analysed, and it is concluded that the scaling errors of current sensors will cause the estimated position to oscillate at twice the fundamental frequency. Based on this conclusion, the phase currents reconstruction technology with SCS is adopted to avoid the impact of scaling errors on rotor position estimation. To reconstruct the phase currents containing HF component, a PWM cycle is divided into two parts, sampling stage and injection stage. By this way, the impact of HF square‐wave voltage injection on current reconstruction can be avoided. Then, the rotor position estimation is realised. The experiments are performed on a 20‐kW IPMSM platform and the results verify the effectiveness of the proposed method.

“…Besides, some compensation schemes are also reported to mitigate the negative impact of measurement errors. [12]- [13]. Nevertheless, when it comes to parallel-VSI systems, it becomes more challenging to compensate sensor measurement errors, as each VSI can only acquire its local measurements.…”

In islanded microgrids, distributed generations (DGs) have been increasingly employed through voltage source inverters (VSIs). When multiple VSIs operate in parallel, it is important to properly share the load power among them. This paper reveals that voltage measurement errors may deteriorate the power-sharing performance by injecting both positive-and negative-sequence circulating currents. To solve this problem, a combined feedforward and feedback voltage control scheme is proposed. Specifically, the feedforward control is utilized to attenuate the negative impact caused by voltage measurement errors, while the feedback control is adopted for the harmonic mitigation. One salient advantage is that the proposed control scheme is fully decentralized and hence does not require any communications among DGs. Finally, Hardware-in-loop (HIL) simulation results are provided for verification.
