摘要
采用状态空间平均法对弧焊逆变电源系统建立了小信号模型,推导系统的传递函数,并对其开环频率特性进行分析。在此基础之上,运用自动控制原理的方法对系统的补偿环节进行设计。最后使用仿真验证了所设计的系统。仿真结果表明,所设计的补偿环节使弧焊电源的快速性和抗扰动能力有了显著的改进,说明设计的正确性。
In this article,the small signal model is derived for arc welding inverter by adopting state-space averaging,and the system transfer functions are established,while open-loop frequency analysis is processed.On the basis of that,the compensating network is designed,finally the design is verified by the simulation,which proves that the design is correct.
