【摘要】 为了对数码发电机波形进行很好的控制,输出稳定的交流电压,本文提出同时对直流测电压和交流输出电压进行闭环控制的方案:当负载变化大时,通过转速闭环控制来间接对直流测电压进行控制;当负载变化不大时,通过调制度M实现电压闭环控制来达到对交流输出电压的控制。这样可以覆盖所有负载范围,达到快速响应和良好的静态精度的目的。更多还原

【Abstract】 The paper put forwards the project of controlling the measure DC voltage and the output AC voltage synchronously to control the output signal.The main method is that when the load changes sharply,the measure DC voltage is controlled through the closed-loop control of the rotation;however,when the load changes stably,the output voltage is controlled through the closed-loop control of the modulation ratio M.In this way,we can control the whole load range,have quick response and a better static accuracy.更多还原
