摘要
提出了一种基于低阶模型参考自适应的交流变频调速系统的设计方案。讨论了自适应控制器在调速系统中的设计方法,并在此控制方案的基础上针对电机的非线性特性引入一个自适应增益补偿表,使自适应控制器能更快速准确地达到预定目标。仿真结果证明,该方案简单有效,系统具有良好的静、动态性能,是一种较为实用的自适应调速控制器。
A low order model reference adaptive control scheme had been proposed for one frequency variable speed regulation system. The guide to the adaptive design of the controller in the system was presented. According to the nonlinear feature of the motor system, an adaptive gain compensation table was introduced in the scheme, the controller can achieve scheduled aim more quickly and exactly. Simulation results demonstrate that the method is simple and effective and the control system is of favorable static and dynamic performance. It is a practical adaptive controller of speed regulation.
