摘　　要：建模是进行控制系统分析和设计的基础,其中磁盘驱动控制系统在便携式计算机和大型计算机中得到了广泛应用。考虑到磁盘驱动读取控制系统的复杂性、非线性以及变量之间的耦合性在不断增加,很难用机理方式建立相应的数学模型,提出了基于控制系统容易获取的输入-输出数据,采用支持向量回归(SVR)建立被控对象的非机理数学模型,该模型结构可以在建模精度和模型结构复杂性之间取得平衡。最后,通过实验分析,论证了采用SVR建立磁盘驱动控制系统数学模型的有效性和优越性。The modeling of HDreading control systembased on SVR is the basis of control systemanalysis and design.HDcontrol system has been widely used in portable computers and mainframe computers.Considering the increasing complexity,non-linearity,and coupling between variables of disk drive read control systems,it is difficult to establish the corresponding mathematical model by mechanism.Based on the easily obtained input-output data,a non mechanism mathematical model of the controlled plant is established by support vector regression(SVR).The obtained model structure can construct a balance between modeling accuracy and model structure complexity.Finally,through experimental analysis,the effectiveness and superiority of using SVR to establish the mathematical model of the controlled object are demonstrated.
