非线性直流电机仿真模型系统的建立

Establishment of Simulation Model System for Nonlinear D.C. Motor

着重考虑直流电机运行在零速度附近所产生的非线性摩擦力的影响，在MATLAB环境下精确地建立起可用于仿真实验以及系统控制器设计的非线性直流电机的仿真模型系统。结合已获得的研究成果，并充分利用SIMULINK软件，在完成非线性系统建模的同时，显示出其软件的强大功效。

: The paper emphasizes and considers influence of nonlinear frictions of a D.C. servo motor which works near the low velocity. The simulation model system of the nonlinear D.C. motor is accurately established under the MATLAB environment, which can be used for the simulation experiment and for the design of the system controller. The work is done by combining with the results of research obtained and making full use of the software of SIMULINK. Effectiveness of the software and its power are demonstrated well.
