| Abstract: | Taking the three-level shunt active power filter（APF） as the researching target,the mathematical model of diode-clamped three-level inverter was described and the LQR control algorithm was derived.And the linear relationship between the controlled variables and state variables was obtained.The proposed algorithm was applied in the inner loop for current control.On the basis of the novel and simplified SVPWM control strategy,the Matlab simulation model was established and the control scheme was tested through the DSP experimental platform.The simulation and experimental results verify the correctness and effectiveness of the proposed scheme. |
