Abstract

This study presents a passivity-based controller for a single-phase active rectifier–DC motor (SPAR-DCM) system. The main objective in the mechanical stage (DCM) is to regulate and maintain the desired angular speed of the motor under sudden load torque changes. Moreover, in the electric power stage, namely single-phase active rectifier (SPAR), the power factor (PF) should stay close to unity. We designed an Online Algebraic Estimator (OAE) to estimate the load torque parameter, adapted to the linear controller based on the exact static error dynamic passive output feedback (ESEDPOF) to minimize its effects. To synchronize the SPAR-DCM system with the grid, we used a second-order general integrator phase-locked loop to generate the necessary reference signals for the ESEDPOF controller. The arithmetic processing is programmed at mediumscale field-programmable gate array Spartan-6 XC6SLX16 through a detailed architecture design in 32 bits and in floating point, according to the standard IEEE-754. Experimental results verified the correctness and effectiveness of the proposed control algorithm. Furthermore, we demonstrated that the PF value is close to unity through power quality measurements.
