Network control experiment device and method for univariate open-loop unstable object

The invention discloses a network control experiment device and method for a univariate open-loop unstable object, and belongs to the technical field of research, experiment and teaching of an automatic control technology, the network control experiment device comprises a controlled object unit, the controlled object unit, an execution mechanism unit and a controller are connected in sequence, and a detection unit is connected with the controller; a light small ball based on airflow suspension is arranged in a vertical transparent pipeline of a controlled object unit, and the height of the small ball serves as a controlled variable, so that an open-loop unstable controlled object is constructed. When the device and the method are used for an experiment, quantitative and continuous disturbance action can be introduced, so that the anti-interference performance of various single-variable control algorithms can be objectively compared and evaluated, time delay and packet loss are set in a video data terminal, an
