| 摘 要： | 针对直线永磁游标电机这一多变量、强耦合的非线性系统, 提出一种基于支持向量机广义逆内模控制的方法. 在证明其数学模型存在广义逆的基础上, 通过支持向量机来辨识原系统的广义逆系统, 经复合后得到具有线性关系的伪线性系统, 然后引入内模控制方法设计附加控制器以增强整个系统的鲁棒性. 仿真结果验证了所提出方法具有良好的解耦性能和抗干扰特性. |

| Abstract: | Due to the multivariable, nonlinear and high coupling characteristics of a linear permanent-magnet vernier machine, a method based on support vector machine(SVM) generalized inverse-based internal model control(IMC) is proposed. The existence of the generalized inverse is verified, then the pseudo-linear system is formed by connecting the original system with the generalized inverse system identified by the SVM. Moreover, the IMC theory is utilized to design extra controllers to improve the robustness of the whole motor drive system. The simulation results show that the proposed control system has good performances of decoupling and resistance to interference. |
