“…From the HIL model presented above, the performance comparison study between the conventional PI controller [29] and the proposed MPC for the compensating current control is herein discussed. The harmonic mitigation in the electric railway system was tested in two situations.…”

“…In the literature review, the DC bus voltage level for APFs [12,15,16,18] and power converter circuits [27,28] is commonly regulated by a PI controller because the steady-state accuracy for the DC bus voltage control was considered. From the previous work [29], the DC bus voltage control loop using the PI controller was suitably designed. Therefore, the PI controller parameters and the reference DC bus voltage in [29] are defined for DC bus voltage control in part B.…”

“…From the previous work [29], the DC bus voltage control loop using the PI controller was suitably designed. Therefore, the PI controller parameters and the reference DC bus voltage in [29] are defined for DC bus voltage control in part B. Finally, part C is the compensating current control, which significantly affected the injection performance of the compensating current.…”

“…For the DC bus voltage control, the PI controller was sufficient to regulate the DC bus voltage (V dc ). The PI controller parameters (K p = 0.0554 and K i = 0.7895) [29] were defined for the DC bus voltage loop control. From Figure 9, it can be seen that the V dc is kept constant at the V * dc using the PI controller.…”

An electric multiple unit (EMU) high-speed train is the dynamic load that degrades the power quality in an electric railway system. Therefore, a power quality improvement system using an active power filter (APF) must be considered. Due to the oscillating load current in the dynamic load condition, a fast and accurate harmonic current-tracking performance is required. As such, this paper proposes the design of a model predictive control (MPC) since the minimization of cost function in the MPC process can suitably determine APF switching states. The design technique of MPC is based on the APF mathematical model. This controller was designed to compensate the time delay in the digital control. Moreover, the synchronous detection (SD) method applied the reference current calculations, as shown in this paper. To verify the proposed MPC, the overall control of APF was implemented on a eZdsp F28335 board by using the hardware-in-the-loop technique. The testing results indicated that the proposed MPC can provide a fast and accurate harmonic current-tracking response compared with the proportional-integral controller. In the load changing condition, the MPC was still effective in providing a good result after compensation. The percentage of total harmonic distortion, the percentage current unbalance factor, and the power factor would also be kept within the IEEE Standard 519 and IEEE Standard 1459.
