摘要:
空间矢量脉宽调制(SVPWM)控制中,逆变器存在死区效应和零电流钳位效应,导致电流电压波形畸变,造成转速转矩脉动,控制性能降低。迭代控制死区补偿策略无需检测电流极性,同步旋转坐标系下,构造反电动势观测器得到实际电压 ed、eq矢量控制输出期望电压ed、eq.通过迭代算法将死区效应造成的误差前馈到期望值,补偿死区效应的影响,提高系统控制性能。仿真和实验证明了理论分析的正确性和有效性。
Abstract:
In the control of space vector pulse width modulation(SVPWM),dead-time effect and zero current clamping effect exist,which leads to the distortion of current and voltage waveform,ripples in speed and torque,and reduction of system performance.An iterative compensation method without detecting current polarity is proposed for the dead time effect.In synchronous rotating coordinate system,The position observer calculated the actual anti electromotive force ed、eq?Vector control acquired the reference voltages ed、eq.The error resulted from dead-time effect was feed-forwarded to the reference voltage through the iterative control.Simulation and experiments results prove that the proposed algorithm can compensate the dead-time effect and improve the system control performance effectively.
