运动控制系统中被控对象的模型辨识研究

该文提出的方法以贴片机为例，使用运动控制器的输出激励被控对象，采样获得被控对象的输入输出数据，然后上传至计算机；通过Matlab的系统辨识工具箱，处理采集的数据并且辨识获得被控对象的数学模型，最后对模型的正确性进行了相应的验证。辨识的结果可为运动控制系统的算法研究、仿真及故障诊断等提供相应的依据。

Model Identification of Controlled Object in Motion Control Systems

Using the placement machine as an example, the method proposed in this paper uses the output data of a motion controller to stimulate the controlled o bjec t and samples its input-output data, then transfers the d ata to PC and processes the data, identifies the model of the control object wit h Ma tlab's system identification toolbox. The model is examined for verification at the end. The identified result can be used in motion control systems for control algorithm study, simulation or trouble diagnosis.
