“…However, due to manufacturing and thermal effects, the inductors, resistors, and capacitors can be different from the designed values. Even though the simulation result shows that the scheme in [10] is robust against uncertain filter parameters, the uncertain filter parameters are not considered in the control design. Thus, the robustness is limited.…”

“…The filter parameters are essential for the design procedure. In such model-based control schemes [8][9][10], it is assumed that the parameters in the model are known. However, due to manufacturing and thermal effects, the inductors, resistors, and capacitors can be different from the designed values.…”

A Robust Suboptimal Current Control of an Interlink Converter for a Hybrid AC/DC Microgrid

A hybrid AC/DC microgrid is established with the aim of exploiting numerous types of renewable energy to meet the needs of different loads. The microgrid is decomposed by AC DC sub-grids which are connected by an interlink converter (IC). To maintain the security and reliability of the microgrid, an automatic controller for the interlink converter is needed. In this paper, we propose a Linear Matrix Inequalities (LMI)-based current control method for the interlink converter. As the main features here, the interlink converter permits bidirectional power exchange between both sub-grids when a power-demand imbalance occurs in one sub-grid regardless of the converter system parameters. Simulations with various filter parameters are performed using the Matlab/Simulink software to validate the effectiveness of the proposed controller. In comparison with the existing Linear Quadratic Regulator (LQR)-based current control, the proposed method is more robust against unknown system parameters and high load perturbation.

“…Meanwhile, various control methods are proposed in [8][9][10]. In [8], a mathematical model of the three phase four-switch (TPFS) pulse width modulation (PWM) voltage-source rectifier (VSR) in rotating d q  frame is firstly derived.…”

“…However, a pulse-width modulator is used in controller design in [8] and [9], and then, this will be further complicated in practical application. In order to avoid the using of pulse-width modulator, a novel control method based on finite control-set model predictive control (FCS-MPC) for fault tolerant operation is proposed to reduce harmonic currents and output power fluctuations under unbalanced grid voltages in [10]. Although numerical examples are investigated to show the effectiveness of the aforementioned control methods, there are barely any studies that address DC-link capacitor voltages fluctuation for ESTP-NPC especially in the presence of fault tolerant operation condition.…”

Summary This article presents an experimental evaluation of a three‐phase induction motor drive during pre‐fault and post‐fault operation. A three‐level boost converter is used at the front end of a two‐level voltage source inverter with a current control algorithm, and a predictive torque control is used for induction motor drive. This topology retains the normal operation under open‐circuit or short‐circuit of devices in any one of the inverter legs, and also the dc‐link voltage across the capacitors is balanced. The merits of the proposed scheme are highlighted and compared with existing fault‐tolerant converter topology (B4) using simulation and experimental results. Furthermore, simulation and experimental results of the proposed scheme in the field weakening region are presented to examine the drive operation above base speed.
