“…In general, current/voltage sensors and inverters are typically integrated inside commercial closed-form drives. Additional inverter hardware modification is necessary if external sensors are selected for an FOC drive with an LC filter [ 17 , 18 ]. In contrast, sensorless observer-based estimation is preferred because only the inverter inside the current sensors is used for filter state estimation.…”

For pulse width modulation (PWM) inverter drives, an LC filter can cascade to a permanent magnet (PM) machine at inverter output to reduce PWM-reflected current harmonics. Because the LC filter causes resonance, the filter output current and voltage are required for the sensorless field-oriented control (FOC) drive. However, existing sensors and inverters are typically integrated inside commercial closed-form drives; it is not possible for these drives to obtain additional filter output signals. To resolve this integration issue, this paper proposes a sensorless LC filter state estimation using only the drive inside current sensors. The design principle of the LC filter is first introduced to remove PWM current harmonics. A dual-observer is then proposed to estimate the filter output current and voltage for the sensorless FOC drive. Compared to conventional model-based estimation, the proposed dual-observer demonstrates robust estimation performance under parameter error. The capacitor parameter error shows a negligible influence on the proposed observer estimation. The filter inductance error only affects the capacitor current estimation at high speed. The performance of the sensorless FOC drive using the proposed dual-observer is comparable to the same drive using external sensors for filter voltage and current measurement. All experiments are verified by a PM machine with only 130 μH phase inductance.

A drive train system (DTS) powered by a battery and driving a permanent magnet synchronous motor (PMSM) is discussed in this paper. A two-level, three-phase conventional inverter with no harmonic filters on both AC and DC sides is used as means of power conditioning. This DTS is modeled as a double oscillator according to the mechanical part in an electric vehicle. Two inverter modulation schemes are applied, namely, a hysteresis scheme (non-deterministic) and one based on sinusoidal-triangular waveforms (deterministic). The influence of these modulation schemes on the performance of the DTS is determined by assessing the level of inverter generated harmonics flowing from/to the battery (electrical part) and the motor (mechanical part). The simulated results presented in the paper indicate that the absence of filters can be partly retained by a dispersion of the harmonic energy of the inverter generated spectral due to high frequency switching. This can be achieved by using a hysteresis control scheme and the impact of the filter-less inverter on the DTS performance is limited only by process specifications.
