Data drive type control performance detection device and method

The invention relates to the technical field of control system performance detection, in particular to a data drive type control performance detection device and a data drive type control performance detection method. The device comprises a data preprocessor, a frequency demultiplication processor, a frequency classifier and a performance evaluation device. According to the data drive type control performance detection device and the data drive type control performance detection method, modeling to a system is not needed, calculation is simple and efficiency of an algorithm is high, daily operation numbers in a control system are directly used for calculating, an experiment is not needed, any influence to normal operation of the system cannot be produced, non-invasive and system-friendly effects are achieved, and convenient application in an actual control system is achieved. In addition, detection results of the device are normalized, and the results are easy to understand.
