CONCLUSION:
A
starting peak current controlled, smooth start, robust position sensorless
control of a PMBLDC motor has been presented for solar powered pumping. The
applied starting method takes care of the high starting inrush current to
secure a good lifespan of the drive as well as the PMBLDC motor. The reduction
of the position sensors makes the system compact and cost effective. The
reliability and robustness of the developed drive are verified with both
laboratory and industrial product prototype using d-SPACE (1104) and
TMS320F28377S DSP. The performance and efficiency of the solar MPPT and PMBLDC
motor are captured using DSO and the same is presented here. It is seen that
the efficiency of the solarMPPT is more than 99%. It is also observed that the
starting method is reliable and effective to keep the initial starting current
within the desired limit. A fast settling stable dynamic performance of the
drive is also observed.
