(2)高性能變頻器 隨著控制理論、交流調速理論和電力電子技術的發(fā)展，異步電動機的矢量控制方式得到了充分的重視和發(fā)展，采用矢量控制方式高性能變頻器和變頻器電動機所組成的調速系統(tǒng)在性能上已經達到和超過了直流伺服系統(tǒng)。此外，由于異步電動機還具有對環(huán)境適應性強、維護簡單等許多直流伺服電動機所不具備的優(yōu)點，在許多需要進行高速高精度控制的應用中，這種高性能交流調速系統(tǒng)正在逐步替代直流伺服系統(tǒng)。 同通用變頻器相比，高性能變頻器基本上采用了矢量控制方式，而驅動對象通常是變頻器廠家電動機．并且主要應用于對電動機的控制性能要求較高的系統(tǒng)。
