摘要
针对交流变频调速器抗负载扰动能力差及宽范围调速时遇到的交流模型严重非线性变化的问题,提出了一种新型速度调节器,该调节器运用多种控制策略实现速度闭环控制。这些控制策略有开环控制、模糊控制和变参数PID(比例、积分、微分)控制。根据实时工况选用某种控制策略,使系统具有较好的快速性、精确性。
In AC variable frequency governor there are two problems, i.e., the weak anti-disturbance ability to load variation and the serious nonlinear variation of AC modelduring wide range speed regulation. To solve these problems a new type of speed regulator is put forward, in whichmulti-control strategies are applied to implement close-loop control of speed. The control strategies include open-loop control, fuzzy control and variable parameter PID control. According to the practical operating modes a certain controlstrategy is choosed to make the speed regulation faster andmore accurate.
