基于干扰观测器的PI控制单相正弦脉宽调制逆变电源
The single phase SPWM Inverter controlled by PI Controller based on disturbance observer
The PI control strategy based on disturbance observer is adopted in the single-phase inverter,which is compared with the traditional PI control sufficiently.The comprehensive analysis of this control strategy and the traditional PI control is given in theory,and the system is designed in MATLAB based on this theory ,besides,the control scheme is achieved in the DSP platform by using digital control algorithm.The simulation result and experimental result prove that the proposed scheme can achieve good dynamic and steady-state performance with better ability of harmonic suppression,compared with the traditional PI control,thus verifying the correctness of theoretical analysis,and giving a certain reference to other systematic deign.
