摘　　要：为了在简化控制的前提下提升能馈型电子负载后级的并网逆变环节性能,针对系统后级逆变环节双环控制系统进行了改进,在替换了电流内环的控制方式的前提下,参考万向节死锁的原理,通过拟似演化博弈的方式比较了电压外环受控参数的关系,对其进行了简化与寻优,仿真结果表明,所提出的控制方法相较之原有控制,将受控参数由4个降低为2个,中间母线电压超调量降低29.8%,并网电流谐波畸变率降低25.3%,且能简单地应用于实验中。To improve the performance of the grid-connected inverter of the rear stage of the energy-fed electronic load on the premise of simplifying the control,the double-loop control system of the rear stage inverter of the system is improved.On the premise of replacing the control mode of the current inner loop,referring to the principle of universal deadlock,the relationship between the controlled parameters of the voltage outer loop is compared by means of quasi-evolutionary game,which is simplified and optimized.The simulation results show that compared with the original control,the controlled parameters are reduced from 4 to 2,the overshoot of the intermediate bus voltage is reduced by 29.8%,and the harmonic distortion rate of the grid-connected current is reduced by 25.3%,which can be simply applied to the experiment.
