摘要
变频器转速闭环变频调速系统设计采用无速度反馈装置或脉冲编码器。为避开三相交流异步电动机和变频器的数学模型,利用飞升曲线法简单近似确定各环节的数学模型。再应用工程设计法设计出调节器,使系统满足静态和动态性能指标。
The close loop system of frequency conversion adjusting speed is based on non-speed feedback equipment or pulse coder. For avoiding the math models of three-phase AC electromotor and frequency inverter, adopt the simple similarity of ascending curve method to ensure the math models of every loop. The engineering design method is applied to elect adjuster expediently, thus the system will fill the static and dynamic capability indexes.
