摘要 自适应控制作为现代控制理论的一个分支,在电机调速系统中起着重要的作用。特别是在磁场定向解耦控制中,通过自适应控制或校正技术将能够正确决定磁场的位置和大小,保证磁场与转矩的解耦控制。文章的这一部分从电机的动态模型和状态方程出发,阐明参数随工作点变化而呈现的不确定性的特点;并着重介绍自适应控制或校正算法的原理和方法应用。 As a branch of modern control theory, the self-adaption control plays an important role in the motor speed-adjustmentsystem. Especially in the field-orienting decoupling control, the field position and amplitude could be defined correctly through self-adaption control or correction technology, so as to ensure the decoupling control of field and torque. Starting from the dynamic model andstatus formula of the motor, the uncertainty characteristic of the parameters changing with the working points is presented. Emphasis is puton the principle and method application of the self-adaption and correction algorithm.
