中文摘要：
由于传统双环控制中的PI调节器的参数固定、自适应性差,当受到扰动或参数变化时,系统的动态性能会迅速下降。考虑到无差拍控制可以使系统具备快速的动态响应能力,设计开发出一种基于无差拍控制和双环控制的逆变器控制策略,并将改进后的控制策略应用于微电网的电压频率控制器中。最后通过matlab仿真验证得到：改进的控制器都可以使系统输出电压很好地跟踪参考指令,大大降低THD的值,同时自动补偿负载的扰动,证明了改进后的逆变器控制策略的有效性。
英文摘要：
For the fixed parameters, the traditional PI regulator in double-loop controller has poor adaptive performance, when disturbed or the parameters change, the system dynamic performance decreases rapidly. The characteristic of the deadbeat control strategy is that it can make the system possess very quick dynamic response capability. The deadbeat control principle was used to design a control strategy of inverter, which is applied in the voltage and/~equency controller, and finally Matlab simulation obtained that： the voltage and frequency controller can make the system＇ output voltage track the reference instruction, and greatly reduce the value of total harmonic distortion, while automatically compensate for load disturbance, Finally, it proves that the control strategy of inverter is effective.
