Comparative Analysis of PI and ADRC Control through CHIL
Real Time Simulations of a DC-DC DAB into a Multi-Terminal
MVDC/LVDC Distribution Network

This article presents a deep theoretical analysis of the Active Disturbance Rejection Control (ADRC) regulator for controlling first-order systems, directly compared with a “traditional” Proportional-Integral (PI) controller. Both ADRC and PI controls are discretized and implemented in Control Hardware In the Loop (CHIL) simulations, where a single-phase Dual Active Bridge (DAB) converter regulates the voltage of a node in a medium voltage DC (MVDC), multi-terminal, and multi-level network. Both controllers are subjected to various disturbances, thereby extending the results of software simulations conducted on a single-terminal network.

This article presents an in-depth theoretical analysis of the Active Disturbance Rejection Control (ADRC) regulator for first-order system control, directly compared with a traditional Proportional-Integral (PI) regulator. To complement the theoretical study, ADRC and PI are implemented in a model of a single-phase Dual Active Bridge (DAB) converter to regulate the voltage of a direct current (DC) network.

 

The strengths and weaknesses of the two controllers are highlighted in the presence of various types of disturbances and network parameter variations. Both ADRC and PI controls are discretized and implemented in Control Hardware In the Loop (CHIL) simulations, where a single-phase DAB converter regulates the voltage of a node in a multi-terminal and multi-level medium voltage DC (MVDC) network. By changing the DAB connection points along the MVDC network, the controlled system is subjected to different disturbances, extending the results of software simulations conducted on a single-terminal network.
