[Abstract]:In the actual production process, the controlled object is the motor, which is composed of various control systems. In the modern motor control, the microprocessor is often used as the core controller. The full control drive power electronic device conversion device is used as the corresponding actuator, and the general electric drive control system adopts the speed closed loop control strategy to keep the speed within a certain precision range and to meet the demand of production load. According to the electrical drive input power, mainly divided into current motor drive and AC motor drive. In the case of high speed regulation performance, DC electric drive is generally used. The thyristor has the natural superiority in the high power reversible speed regulation system, so the DC armature reversible speed regulating system composed of the thyristor has been widely used in the high power, high precision and so on. At the same time, the reversible operation and energy feedback braking of DC motor can be easily realized by the thyristor reversible speed control system, and the smooth speed conversion can be realized in the process of positive to reverse and reverse to positive turn, at the same time, The armature current has no dead zone, which ensures the continuity of armature current. It is one of the common methods to study the speed regulation system by simulation. The simulation can simplify the time of setting up the actual speed control system and improve the stability and security. In this paper, a simulation system is built by using the basic module of Simulink and the professional module of electric toolbox under MATLAB. The mathematical model of DC speed regulation system is established by script command, which is used to calculate system parameters and connect seamlessly with simulation. Can be applied to engineering. Finally, GUI graphical user interface is used to control the simulation and script, and the results are obtained.
