This work presents a sensorless control scheme for a solar photovoltaic (PV) battery fed permanent magnet synchronous motor (PMSM) drive for three wheeler vehicles application. In addition to this., an approach to vehicle design., modeling and energy calculations based on the Indian driving cycle (IDC) is analyzed. The system consists a battery., which is directly connected to DC link., while a rooftop solar PV panel is installed to regulate battery performance. To extract the peak power in various environmental conditions., a modified Perturb and Observe (P&O) technique is utilized., which improves the dynamic speed during sudden change in irradiance as well as steady state error. Furthermore., an adaptive flux observer (AFO) based sensorless technique is utilized for speed and position estimation. The presented speed and position sensorless technique is developed to eliminated DC offset and harmonics from the estimated flux with a simple structure. The adaptive nature of this observer makes it effective for wide range of speed. The validity and performance of the system are assessed with various obtained results.
