Abstract
With the rapid development of high technology like computer technology and information technology, the simulation technology is also promoted rapidly. Currently, MATLAB is the most common simulation software used in control field. The simulation and design of the control systems can conveniently be achieved using the MATLAB control system toolbox.
This thesis describes MATLAB simulation technology and the concept, characteristics and development of theory of automatic control. Furthermore, the application of MATLAB software in the experiments teaching of theory of automatic control is introduced basing on the examples. The function of MATLAB and how to simulate the experiments of theory of automatic control in SIMULINK are analyzed. The experiments include: MATLAB-based unit step response of second order system, the stability analysis for control system, measurement of system frequency characteristics, cascade compensation of continuous system (lead compensation, lag compensation, lag and lead compensation), MATLAB-based frequency domain analysis, general design of disk drive control system.
In conclusion, simulating and analyzing the experiments of the theory of automatic control using MATLAB is the important research method of the theory automatic control. Not only the experimental methods are modified, but also the experiment efficiency and the experiment level are improved.
