Due to unpredictable factors, the model predictive direct power control (MPDPC) exists weak robustness when the parameters change of three-phase rectifying converter. Therefore, this paper introduced Fractional Active Disturbance Rejection Control (FADRC) into the MPDPC system to improve the robustness of rectifying converter, that is, the power loop of PID controller in conventional model predictive control is replaced by FADRC. In order to verify the effectiveness of the proposed control strategy in this paper, a model of three-phase rectifying converter is established in MATLAB, and the simulation is conducted. Compared with the control effects of the MPDPC with PID (MPDPC-PID) control strategy and MPDPC with Linear Active Disturbance Rejection Control (MPDPC-LADRC) under different operational scenarios, the simulation results demonstrate that the MPDPC with FADRC (MPDPC- FADRC) strategy has best disturbance rejection capability, robustness and rapidity, and it can significantly reduce the voltage fluctuation of DC bus. This study can provide a valuable guidance and reference for the design of the efficient and stable three-phase rectifying converter.

“…In general hysteresis current controller (HCC) is implemented as the current controller because it provides fast response, good accuracy and it is implementation in practical application is quite simple [6]. Along with the above advantage it's also has disadvantages like it is not capable to use the zero output state of single phase inverter which can be used to improve the output voltage waveform, the output voltage is switched from +VDC to -VDC to control the output current to be still in the band hence the nature of the output voltage is bipolar in nature which result in higher in higher harmonic content, it also exhibits high switching frequency [7]. The discussed disadvantages of the HCC like incapability of using zero output state and bipolar nature of output voltage can be overcome by using double band hysteresis current controller.…”

A comparison between single band hysteresis current controller and double band hysteresis current controller for a single phase grid integrated pulse width modulated VSI is highlighted in this paper. Disadvantages of the HCC like incapability of using zero output state and bipolar nature of output voltage can be overcome by using double band hysteresis current controller. The output of double band controller (DBC) switches between +VDC and zero or -VDC and zero voltage levels resulting in unipolar nature output voltage which is better than the bipolar one in terms of the harmonic content and output current ripple. It also achieves the zero state output voltage and the switching frequency is also reduces in case of DBC. The studied system is modeled and MATLAB/Simulink environment.

“…The THD of the output is another important index that can reflect good performance of the three-phase VSI. A high THD will degrade the current quality and lead to the overheating of the equipment [15].Therefore, decreasing the THD is another goal that researchers are pursuing [16,17]. For this purpose, a seven-segment technique of SVPWM will be chosen to determine the switching sequence because of the low THD.…”

The three-phase voltage source inverter has been widely used in a number of industries in the recent years. Although the control technique of the three-phase voltage source inverter has been growing toward maturity, research into obtaining a better steady-state performance is still a hotspot. In this paper, a modified controller is proposed to control the three-level, three-phase voltage source inverter with a resistive-inductive load. The controller uses Laguerre functions to modify the model predictive control in order to reduce the computation burden and obtain more precise results. Then the required reference voltage can be calculated by the modified model predictive control with the voltage detection of the load and the current compensation. The required reference voltage will be used to determine the switching sequences by space vector pulse width modulation. Extensive experiments demonstrate that the modified controller can help a three-level, three-phase voltage source inverter with resistive-inductive load to achieve low total harmonic and better steady-state performance.
