Experiment module for automatic control principle

The utility model relates to an experiment module for an automatic control principle, which comprises an analog circuit based on the contents of a linear system frequency response analysis experiment, a signal generator output end which provides sinusoidal signals for the analog circuit, a signal output end which is used for outputting the measurement signals of the analog circuit to an experimental platform, a signal input end which is used for transferring the measurement signals of the analog circuit to the signal output end, and a peripheral equipment connecting slot which is connected with the experimental platform, wherein the analog circuit is integrated in the experiment module for the automatic control principle. The experiment module for the automatic control principle does not require an experimenter to spend too much time in preparing components and establishing an experimental circuit, and thereby the teaching experiment time can be saved.
