The Research on the Automatic Measurement of Frequency Characteristics of Opto-electronic Platform
A new frequency characteristic test method is proposed based on the digitization characteristics of optoelectronic platform servo system. First a digital processing controller is used to automatically test me entire process and tested data are uploaded to a PC through CAN-bus, and then the tested data are transferred into accurate transfer function with the Levy method Here we discuss the testing steps, the data processing, the extraction, the Bode diagram plotting and the model identification in detail. The corresponding experiments are carried out, and the results show that the method is simple with the features of high efficiency, high precision and engineering feasibility.
