Abstract
This paper presents a passivity-based control (PBC) design methodology for three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems where reduced harmonic distortions for the nonlinear load, reduced output voltage overshoot, and a restricted settling time are required. The output filter design and modification for efficient control and existing challenges with the assignment of scaling coefficients of the output voltage, load, and inductor currents are addressed and analyzed. Notably, special attention is given to the modulator saturation issue through implementing an accurate converter model. Applications of the two versions of PBC in three-phase voltage source inverters using stationary αβ and rotating dq frames for a constant frequency of the output voltage are presented. Furthermore, the influence of the PBC parameters on the power converter performance is investigated. A comparative simulation and the experimental results validate the effectiveness of the presented passivity-based control design methodology.
Highlights
The control design of single-phase and three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems has been extensively discussed for the last four decades [1,2,3,4,5,6]
The first one is based on the single input single output (SISO) approach where only the output voltage is measured and controlled, while in the second approach, a multi input single output (MISO) controller is employed to regulate the output voltage based on the output current, inductor current, and the output voltage measurements
The calculations of IPBC2 in the stationary αβ frame using only the Clarke transformation without any interactions and without the angular speed ωm as additional input are faster than the calculations of IDA–passivity-based control (PBC) [27] in the rotating dq frame
Summary
The control design of single-phase and three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems has been extensively discussed for the last four decades [1,2,3,4,5,6]. The PBC control strategies are implemented in renewable energy sources and energy storage systems [7]. Two control types for the UPS systems are implemented in order to meet the standard requirements that are defined by IEC 62040-3 [8] for nonlinear rectifier resistive-capacitive (RC) load types. A proportional–integral–derivative controller (PID) is a standard SISO control (e.g., designed based on the quasi-continuous transfer function [9]).
