高动态性能变频调速控制方式的比较和应用

Comparison and application of ac adjustable speed drivesystems with high dynamic performances

对目前变频器厂家广泛采用的高动态性能交流调速控制方式:矢量控制方式(VC)和直接转矩控制方式(DTC)的控制原理、特点和控制特性进行了分析比较,并指出在工程实际应用中应根据控制对象的不同选择合适的控制策略。

This paper analyzes the difference on the control principles and distinguishing features between vector control and direct torque control. Those two high dynamic performances control modes are being adopted in many frequency conversion companies. It shows that different control strategies should be chosen in real engi- neering application based on different control objects.
