“…3. The values for the resistance and inductance used are 0.225 Ω and 2 mH respectively, which results in: The dynamic optimization parameters (λ, q) were chosen after an in depth evaluation as in [22] and after a number of trial and evaluation attempts, a value of λ=1 and q=5000 is selected which allows fast tracking of the command signal with relatively minimal ripple.…”

-This paper presents a model predictive control for shunt active power filters in synchronous reference frame using space vector pulse-width modulation (SVPWM). The three phase load currents are transformed into synchronous rotating reference frame in order to reduce the order of the control system. The proposed current controller calculates reference current command for harmonic current components in synchronous frame. The fundamental load current components are transformed into dc components revealing only the harmonics. The predictive current controller will add robustness and fast compensation to generate commands to the SVPWM which minimizes switching frequency while maintaining fast harmonic compensation. By using the model predictive control, the optimal switching state to be applied to the next sampling time is selected. The filter current contains only the harmonic components, which are the reference compensating currents. In this method the supply current will be equal to the fundamental component of load current and a part of the current at fundamental frequency for losses of the inverter. Mathematical analysis and the feasibility of the suggested approach are verified through simulation results under steady state and transient conditions for non-linear load. The effectiveness of the proposed controller is confirmed through experimental validation.

“…The same concept is used in [21] by Mendalek, where the voltage level of the dc side is regulated using a linearizing feedback control. In [22], Wang developed a simplified MPC method for shunt APFs. Da Silva in [23] proposed a compensation algorithm used to extract the reference currents.…”

“…• the communication protocol between the PL and PS uses a 32-bits bus, • with the chosen T c = 100ns, the coefficients c 1 , c 2 , c 3 and c 4 have small values and need 30 bits in the fractional part in order to be coded, • and all the variables in the VSR p.u. model vary in the interval [-1,1[, the FPGA variables are coded on 32 bits using the format 32Q30 which is enough to accelerate the communication process and to ensure good accuracy.…”

“…Indeed, all these systems need an efficient and performing power converter to be connected to the grid. In this context, new computationally intensive control techniques have to be developed to achieve the expected precision and dynamic performances [1]- [3]. These expectations will be even more stringent with the generalization of the use of wide bandgap power switches that are working at very high switching frequency [4].…”

This paper analyses the capacity of a new FPGAbased System-on-Chip (SoC) platform for the control of electrical systems. These new SoC platforms integrate both an FPGA fabric and a powerful processor. Among these platforms the Xilinx Zynq-7000 All Programmable (AP) System on-Chip is evaluated. The chosen algorithmic benchmark consists on a realtime simulation of a Voltage Source Rectifier (VSR) connected to the grid and supplying a resistive load. This VSR is controlled via a Model Predictive Control technique. The VSR dynamical model is implemented in the FPGA fabric of the Zynq-7000 while the predictive controller is implemented in its processing part. Both software and hardware parts of the benchmark are challenging. The model predictive control technique is computationally intensive. Moreover, the VSR model should approximate a quasi continuous-time behavior which implies that its dynamical model has to be executed at very high frequencies (10 MHz). Realtime simulation results are presented and compared with double precision off-line software simulation results.Index Terms-System-on-chip, real-time simulator, Zynq-7000 board, model predictive control, hardware/software design 978-1-4799-7800-7/15/$31.00 ©2015 IEEE

A multi-loop controller for gird-connected voltage source converters with LCL filter is proposed in this paper. The controller consists of three segments -inner predictive current controller, outer voltage vector controller, and the command voltage modifier. The whole controller is applied to converters based DRs in microgrids, and regulate the load terminal voltage with zero steady-state error even under unbalanced conditions. Selected results from simulation studies conducted on the performance of the controller under balanced and unbalanced conditions both in island and grid-connected mode are presented.
