 Abstract

The Matlab is playing an important part in the scientific research, whether we adopt optimum simulation of Matlab decide whether we can get ideal simulation results. This text takes the split-loop direct current velocity-adjust system for example, and we can get different simulation results by choosing different simulation. We study the simulation of Matlab by comparing the simulation results. At last we summarize how we can achieve the superior choice of simulation of Matlab in the simulation process.
Then this paper introduces the method of the simulation and modeling of DC motor speed regulating in electrical motor drive. Simulation is consistent with theory analysis, t can take the place of the parts of real objects experiment.
At last ,the application of Matlab in the teaching of DC speed control system with dual-closed loop is discussed in the paper. Firstly, the simulation of the mathematic model which based on the analysis of DC speed control system’s theory is introduced. Parameters can be flexibly modulated; the parameter design can be optimized as well. Then, the simulation by the electric theory chart is finished. The speed control system’s anti-disturbing ability is analyzed. Engineering design of DC speed control system with dual-closed loop, choice of regulator, the parameters of calculation and validation; dynamic structure of the system are given, and establish a dynamic, anti-load disturbance of the MATLAB / SIMULINK simulation model. Starting analysis system and the speed of the current wave simulation and DC speed control system with dual-closed loop converter so that more reasonable and perfect the system.
