This paper presents a finite control set model predictive control (FCS-MPC) strategy for the AC/DC matrix converter used in grid-connected battery energy storage system (BESS). First, to control the grid current properly, the DC current is also included in the cost function because of input and output direct coupling. The DC current reference is generated based on the dynamic relationship of the two currents, so the grid current gains improved transient state performance. Furthermore, the steady state error is reduced by adding a closed-loop. Second, a Luenberger observer is adopted to detect the AC input voltage instead of sensors, so the cost is reduced and the reliability can be enhanced. Third, a switching state pre-selection method that only needs to evaluate half of the active switching states is presented, with the advantages of shorter calculation time, no high dv/dt at the DC terminal, and less switching loss. The robustness under grid voltage distortion and parameter sensibility are discussed as well. Simulation and experimental results confirm the good performance of the proposed scheme for battery charging and discharging control.

“…Compared with "AV method", SVPWM not only increases the maximum voltage transmission ratio from 0.5 to 0.866, but also achieves digitization easily. As a result, SVPWM is currently widely applied [15][16][17]. Therefore, for USMC, the harmonic analysis of output voltage under SVPWM is of important significance.…”

Abstract:In a matrix converter, the frequencies of output voltage harmonics are related to the frequencies of input, output, and carrier signals, which are independent of each other. This nature may cause an inaccurate harmonic spectrum when using conventional analytical methods, such as fast Fourier transform (FFT) and the double Fourier analysis. Based on triple Fourier series, this paper proposes a method to pinpoint harmonic components of output voltages of an ultra sparse matrix converter (USMC) under space vector pulse width modulation (SVPWM) strategy. Amplitudes and frequencies of harmonic components are determined precisely for the first time, and the distribution pattern of harmonics can be observed directly from the analytical results. The conclusions drawn in this paper may contribute to the analysis of harmonic characteristics and serve as a reference for the harmonic suppression of USMC. Besides, the proposed method is also applicable to other types of matrix converters.

“…They are scalar techniques, pulse width modulation (PWM), predictive control, and direct torque control (DTC) [3].The Venturini method [4] is the first scalar technique, which obtains the duty ratio of each switch directly by calculating the function of the instantaneous value of the input voltage and the reference value of the output voltage. The Space vector modulation [5] (SVM) is based on the instantaneous space vector representation of input and output voltages and currents and it exploits the pulse width modulation, which was developed and improved in the 1990s. The modern technique, predictive control [6], [7] evaluates the effect 52 of each possible switching state by a cost function.…”

An advanced direct torque control (DTC) technique using Model predictive control (MPC) is proposed for matrix converter (MC)-based permanent-magnet synchronous motor (PMSM) drive system, which reduces the torque ripples, does not need the duty cycle calculation, and ensures the fixed switching frequency. Analytical expressions of change rates of torque and flux of PMSM as a function of MC -dqo components are derived. The predictive model of PMSM and MC is realized by means of State model. Then, the advanced MC-fed DTC algorithm is implemented based on Cost function evaluation. The simulation results exhibit remarkable torque ripple reduction with the help of MPC. As a result, the proposed strategy is proved to be effective in minimizing the torque ripples for MC-based PMSM drives. Keywords Direct torque control (DTC), matrix converter (MC), permanent-magnet synchronous motor (PMSM), Model predictive control (MPC), and Cost function
