给出一种最小二乘支持向量机（Least Square Support Vector Machine，LS-SVM）广义逆内模控制方法。利用LS-SVM辨识这类系统的广义逆，再与原被控系统串联成具有近线性伪线性的开环控制系统，引入内模控制使其变成稳定的闭环控制回路，将这种方法应用在球磨机控制系统中。经仿真分析，该方法不依赖于被控系统精确的数学模型，实现了小样本训练的准确辨识，提高了系统的动态响应，并与内模控制相结合，使其闭环控制系统鲁棒稳定性增强。

A LS-SVM generalized inverse internal model control ( IMC ) was proposed, which employs least square support vector machine ( LS-SVM) to identify the system’ s generalized inverse, and then to cascade with original controlled system to become a pseudo-linear open-loop control system and to generate a steady closed-loop control after the internal model control to be adopted.Applying this method to the ball mill control system shows that this method doesn’ t rely on the exact mathematical model of the controlled system and it can accurately identify the small simple training and enhance the system’ s dynamic response.Combining with the internal model control can improve both robustness and stability of the closed loop control system.
