“…Besides, IDA-PBC gives excellent tracking of time-varying signals such as the current reference in case of non-linear loads [15]. PBC has been investigated extensively for the control of dcdc converters [16][17][18][19][20], rectifiers [21,22], single-phase inverters [23][24][25][26] and most recently for the control of three-phase inverters [15,[27][28][29][30][31][32], modular multilevel converter [33,34], active power filter [35], dual active bridge converter [36] and solid-state transformers [37]. Serra et al [27] have applied IDA-PBC design procedure for voltage control of stand-alone 3 ϕ inverter and have compared its performance with a PI-based controller.…”

A voltage-source inverter (VSI) is a key component of a distributed generation unit and an uninterruptible power supply. In this study, a three-phase VSI control using interconnection and damping assignment passivity-based control (IDA-PBC) approach has been revisited and analysed on aspects such as voltage gain, output impedance, transient response, stability and steady-state error. It is shown that in the case of accurately known filter parameters and perfectly zero initial conditions, theoretically, the voltage controller would exhibit unity voltage gain and zero output impedance. It is also shown that the IDA-PBC-based voltage controller exhibits a second-order response to a step input. This property has been utilised to propose a novel systematic procedure for tuning of the IDA-PBC gains based on the transient response specifications. The tuning method reveals that the gains for the outer voltage and inner current loops are related to each other and should not be separately tuned. The presented analysis and the proposed tuning method for controller gain have been tested through simulation studies. The concepts were further validated on a laboratory scale prototype of a three-phase VSI for balanced, unbalanced and non-linear loads.

“…Like PBC, IDA-PBC is applied in various under actuated systems including mechanical, electrical, and electromechanical [28] systems. Recently, IDA-PBC is also applied for the control of various PEC-based applications [29] such as grid connected front end converter [30], DC-DC boost converter [31,32], current source converter connected with super-conducting magnetic energy storage (SMES) [33], solid-state transformer [34], multilevel converter [35] etc. In addition, IDA-PBC is proposed in [36] for the energy management of an interconnected FC and ultracapacitor-based hybrid system.…”

“…Hence, a complementary PI is added with IDA-PBC in [31] for the control of DC-DC boost converter supplying constant power load. IDA-PBC with integral action is applied for the control of a bidirectional grid connected inverter of a grid connected PV system in [39] and for the control a multilevel converter in [35]. The application of IDA-PBC can further be extended for the damping improvement and energy management of a grid connected microgrid, which is capable of operating in both grid-connected and -isolated modes.…”

In this study, energy management and damping improvement of a DC microgrid are proposed by using an interconnection and damping assignment-passivity-based control (IDA-PBC) technique. The control technique is applied for (i) the grid connected inverter and (ii) the DC-DC converters connected with fuel cell and battery of the DC microgrid to control the DC bus voltage. The IDA-PBC generates the control laws with the desired energy function for the current controller of the converters based on the generation from the renewable power generators and load demand. In addition, an integral action is added with the IDA-PBC control laws to reduce the steady-state error in the DC bus voltage. The parameters of the IDA-PBC technique are tuned based on the state of charge of the battery and grid availability for a smooth transition between the operating modes and better energy management. It is proved that the derived energy function satisfies the Lyapunov stability criterion. Simulations are carried out in MATLAB/Simulink to test the performance of the proposed control technique. The results show that the proposed technique provides the desired damping and energy management.

“…Researchers have done a great deal of study on the control strategies of M3C [12][13][14][15]. Although the M3C is a feasible topology, the nine branches lead to high cost and the numerous circulating current paths also increase the difficulties of circulating current analysis and suppression [16]. In 2011, Baruschka and Mertens proposed a new direct AC/AC topology called the Hexverter.…”

A fractional frequency transmission system (FFTS) is the most competitive choice for long distance transmission of offshore wind power, while the Hexverter, as a newly proposed direct AC/AC converter, is an attractive choice for its power conversion. This paper proposes a novel control scheme characterizing the global stability and strong robustness of the Hexverter in FFTS applications, which are based on the interconnection and damping assignment passivity-based control (IDA-PBC) methodology. Firstly, the frequency decoupled model of the Hexverter is studied and then a port-controlled Hamiltonian (PCH) model is built. On this basis, the IDA-PB control scheme of the Hexverter is designed. Considering the interference of system parameters and unmodeled dynamics, integrators are added to the IDA-PB controller to eliminate the steady-state error. In addition, the voltagebalancing control is applied in order to balance the capacitor DC voltages to obtain a better performance. Finally, the simulation results and experimental results are presented to verify the effectiveness and superiority of the IDA-PB controller.
