“…D(s) and Q(s) in Fig. 6 respectively provide the band-pass and low-pass filtering characteristics to i' and qi', which can attenuate harmonics and noise of the measured current im [34]. And provided ω'=ω, qi' in Q(s) will always be π/2 lagging i' in D(s) independently of ω' and k, verifying that the SOGI-based filtering structure can serve as the quadrature signal generation (QSG).…”

“…Though characterized by a significantly-low computation burden and independent of plant models, the linear prediction has a poor accuracy for delay compensation. The Smith predictor [28], the current observer [32], [34] and the model predictive control [33] can ideally completely compensate the delay in control systems, which however require precise plant models and are thus sensitive to plant parameters. Phase-lead compensators [27], [29], [30] can be used to compensate the delay of a certain-frequency component.…”

“…The control variables can only be selected among the possible switching states in each control cycle, so the control variables are not absolutely optimal but relative, and the switching frequency of the converter in FCS‐MPC is not fixed. CCS‐MPC calculates a continuous voltage reference by an online optimization algorithm and then uses PWM method to realize the voltage reference by the combination of several switching states in each cycle . Comparing with FCS‐MPC, CCS‐MPC can get absolutely optimal control variables with fixed switching frequency, while complex calculation is required.…”

Summary Model predictive control (MPC) is becoming a popular topic in the control of AC motor and power electronic converters because of its high dynamic performance and multitarget optimization ability. However, steady‐state error still exists in conventional MPC method because of unavoidable errors of model parameters. In addition, time delay in digital control also affects the performance, and even stability of MPC. In this paper, an offset‐free robust model predictive control (OFR‐MPC) method is proposed for the current control of three‐phase induction motor (IM). An incremental model is adopted to improve the parameter robustness and to realize offset‐free prediction. An improved current observer is designed to realize time‐delay compensation in control variable optimization. In addition, the improved current observer is also acting as a filter to solve the problem of noise amplification effect of the incremental model. The proposed method can also be applied to other AC motors and power electronic converters. Simulations and experiments have been implemented to verify the performance of the proposed OFR‐MPC method.

“…The deadbeat current control is based on the mathematical model of the grid-connected inverter and depends on the actual electrical parameters of the main circuit. Theoretically, no static-state error can be achieved in [9][10][11][12]. Because of its fast current transient response, accurate current tracking characteristic, and all digital control, the deadbeat current control has been applied more often.…”

In the grid-connected inverter based on the deadbeat current control, the filter inductance variation and single update PWM affect the distortion of the grid current, stability, and dynamic of the system. For this, a double update PWM method for the deadbeat current controller in three-phase grid-connected system is proposed, which not only effectively decreases the grid current distortion and control delay, but also improves the system stability and dynamic response speed due to reducing the characteristic root equation order of the closed-loop transfer function. The influence of the filter inductance deviation coefficient on the system performance is analyzed. As a conclusion, the corresponding filter inductance deviation coefficient in the system critical stability increases with increase in the parasitic resistance of the filter inductance and line equivalent resistance and decreases with increase in the sampling frequency. Considering the system stability and dynamic response, the optimal range of the control parameters is acquired. Simulation and experimental results verify the effectiveness of the proposed method.
