【摘要】 电压型逆变器的控制目标为电压,而一个系统要获得高性能就必须控制其电流,如何在电压型逆变器上进行电流控制?本文运用的电流跟踪 PWM 方法就圆满地解决了这一问题。系统采用滑差频率矢量控制方式提高其动静态性能,使用价格便宜、功能较强的 MCS-51系列单片机8031实现控制和运算功能,使系统结构简单,实用性强,有推广价值。更多还原

【Abstract】 The control objective of voltage source inverter is voltage, but every system with high performance is obtained by controlling current.How do get current control in voltage source inrerter?This paper introduces the method of current trace PWM and satisfactorily solves aforementioned problems. This System improves its dynamic and static state performance by Slip-freguency vector control principle.MCS-51 Single-chip microcomputer 8031 with low price and high perfomance is used to relize control and caeulate function,the system is changed into simple structure,widespread practicality and has popularized price.更多还原
