DSPACE implementation and experimentation of Power Field Oriented Control for motor-pump fed by intermittent renewable sources

This paper presents the experimental results of an original control strategy for motor-pump implemented on a dSPACE controller board. The Power Field Oriented Control strategy developed in this paper is used to drive a motor-pump fed by intermittent renewable sources. This system is dedicated to autonomous applications for pumping or water desalination for remote areas without access to hydraulic and electric networks. This control strategy allows controlling the DC bus voltage without using batteries in the system. The DC voltage control is achieved through the control of the inverter used for the motor-pump. Experimental results for variable power source are presented and confirm the effectiveness of the proposed control strategy.
