双闭环串级调速系统的工程法设计

An Engineering Design for the Cascaded Speed Adjustment System of Double Closed Loop

本文根据双闭环串级调速系统的数学模型,按照工程设计的方法,在转差率S为0—1范围内,分别对电流调节器和速度调节器的PI参数进行了计算,其参数和动态性能指标受转差率S的影响很小,适应较宽的调速范围。本文举出了一个设计实例,并提出参数测量的实验方法。

Based on the mathematic model of the caseaded speed adjustment system of doubleclosed loop and througth application of engineering design method for the system, the PIparameters of current regulator and speed regulator are calculated separately, when thevalue of the slip S variates from 0 to 1. It is shown that the effect of slip on theparamefers and the dynamic performance indexes of the system is very little. So it may beapplied to a wide range of speed control. A practical design example of the system is dis-cussed. The test methods for measuring parameters of the system are also presented.
