Frequency Adaptive Digital Filter Implementation of Proportional-Resonant Controller for Inverter Applications

Compel, 2018
The Proportional-Resonant control is used in control schemes that directly act on AC variables avoiding synchronous frame transformation. In this paper, the PR controller is realized using an IIR digital filter and implemented using direct form II ...

Comparative analysis of Cuk converter with proportional integral controller & proportional resonant controller

International Conference on Communication and Electronics Systems, 2019
This study presents comparison between two different control techniques for PFC converters with less total harmonic distortion (THD). The PR current controller provides the gain at resonant frequency & eliminates steady state error.

Optimized tuning method of stationary frame Proportional Resonant current controllers

2014 International Power Electronics Conference (IPEC-Hiroshima 2014 - ECCE ASIA), 2014
This paper presents an optimized tuning method of Proportional Resonant (PR) current controllers implemented in the stationary frame. The approach consists of defining three operation regions based on behavior of the closed loop poles, and of determining simplified tracking and disturbance transfer functions for each of these regions.

Multi-Frequency Proportional-Resonant Control for Wave Power Generation System

Advanced Materials Research, 2013
A grid voltage vector oriented proportional resonant (PR) control strategy is applied to the grid current control of the float-type wave power generation system. Compared with the conventional double closed-loop proportional integral (PI) control method, the proposed multi-frequency PR control method can realize zero steady-state error in AC input ...

Study on Proportional Resonant control strategy of single-phase SVG

2012 IEEE International Symposium on Industrial Electronics, 2012
Single-phase Static Var Generator (SVG) is widely used in fields like electrified railway and Distribution Generation (DG) etc. However, it has special requirements and difficulties, e.g. a single-phase SVG is not easy to achieve satisfactory performance of tracking the AC reference comparing with the three-phase one.

Proportional resonant controller for a 27-level asymmetric multilevel STATCOM

2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 2017
In this paper a 27-Level Asymmetric Multilevel STATic COMpensator is presented aimed to compensate reactive power. The STATCOM is controlled with a master-slave approach, where the master loop is responsible to regulate the DC voltage using a Proportional-Integral controller, while the inner loop is in charge to track the reference currents through a ...

Robust Stability Design for Inverters Using Phase Lag in Proportional-Resonant Controllers

IEEE transactions on industrial electronics (1982. Print)
Engineers often reduce proportional-resonant (PR) controllers to simpler proportional controllers, neglecting the phase lag at midfrequencies. This reduction can lead to the incorrect assumption that a single-loop-control inverter with grid-side current ...
