摘　　要：针对两电机变频调速系统中非线性逆模型辨识困难的问题,提出基于支持向量机的逆系统控制新方法。在同步旋转坐标下,建立两电机变频系统的数学模型,并进行了可逆性分析。通过支持向量机回归的方法来辨识构造原系统α阶逆系统,将辨识出的逆系统串接在原系统之前构成伪线性复合系统,再设计附加闭环控制器进行控制。试验结果表明,该方法不依赖于系统模型,对电机参数摄动及负载扰动具有较强的鲁棒性。To deal with the inverse model identification problems in two-motor variable frequency speed- regulating system, Proposed a new inverse control method based on support vector machine （SVM）. On the basis of the mathematic model and reversibility analysis of the two-motor variable frequency system, th-order inverse control method based on support vector machine （SVM） is utilized as a regression tool to approximate the original system. Introduced the two-motor variable frequency system into the pseudolinear system, then designed a close-loop adjustor to control the subsystem. The experiment results demonstrate that the combined method does not depend on the accurate mathematical model, and has the strong robustness to variation of parameters and load torque disturbance.
