This document is the automatic control principle experimental instruction manual made by the Automatic Control and Testing Teaching Experiment Center of the School of Automation Science and Electrical Engineering of Beihang University. It mainly introduces the hardware and software composition of the experimental system, and the experimental content includes basic experimental contents and research experimental contents. The basic experimental contents include typical loop experiments, frequency characteristic tests, control system series correction, PID controllers, state feedback and observers, sampling system research experiments, nonlinear loop experiments and other types of control theory experiments, while the research experiments are more flexible, using hardware drivers to achieve basic data input and output, MATLAB can achieve control algorithm and system model construction. The combination of the two can realize any experimental system, so that the experimenter can conduct relevant control theory research.
The manual introduces the experimental setup used by the Automatic Control Principle course at Beijing University of Aeronautics and Astronautics. It details the data acquisition board, the simulation hardware, and the MATLAB‑based software environment required for the experiments.
It also provides step‑by‑step instructions for connecting the hardware, configuring the MATLAB/Simulink models, and performing measurements and analysis, allowing students to conduct both basic and research‑oriented control experiments. This manual is written in Chinese.
