摘要:
针对单相逆变器给定信号和反馈信号均为正弦量,在静止坐标系下采用比例积分调节器不能实现无差跟随且对于周期干扰信号不能实现无差抗扰动,从而导致输出稳态精度受到影响的问题,采用坐标变换将静止坐标系下的交流信号变换到旋转坐标系下的直流量。采用电压环在同步旋转坐标系下的比例积分控制电流环在静止坐标系下的比例控制的策略,进行电压反馈解耦,简化控制系统的设计,改善系统的鲁棒性。最终,SIMULINK仿真验证了上述理论的可行性。
Abstract:
Single-phase inverter given signal and feedback signal are sinusoidal,proportional-integral regulator can’t be achieved with zero steady-state error and the periodic interference signal can’t be achieved with indifferent disturbance in stationary coordinate system,which affects the output steady-state accuracy problems.Single-phase coordinate transformation is adopted to transform AC signals in stationary reference frame to straight flow in a rotating coordinate system.Synchronous reference frame proportional-integral (SRFPI) based outer voltage control and inner inductor current control in stationary reference frame are used in inverter control system.And voltage feedback decoupling is introduced to simplify control system design and improve system robustness.Eventually,Simulink simulation verifies the feasibility of the above theory.
