This paper presents an adaptive control strategy for a boost rectifier supplying a varying resistive load. The interconnecting boost rectifier is supplied to a permanent magnet synchronous motor (PMSM) machine connected to a diesel engine. An online load estimation technique has been proposed to determine changes in the DC terminal's loading conditions. Simultaneously, a feed-forward controller is formulated to enhance the performance of the DC link voltage and converter currents by modifying the conventional voltage-oriented control technique. The proposed analysis has been validated in the MATLAB Simulink environment. The designed technique provides better converter control and voltage stability under dynamic conditions.
