摘　　要：在研究自抗扰控制技术的基础上,以MATLAB/SIMULINK为仿真平台,编写M_Funtion程序实现特殊非线性函数、应用S_Funtion定制跟踪微分器和扩张状态观测器等新型动态系统模块、利用子系统封装技术完成控制律组合和常用自抗扰控制器算法,按照模块化建模思想,创建了用户自定义的自抗扰控制器模块库。通过串级调速自抗扰控制系统的仿真实例,说明利用该模块库,实现了自抗扰控制技术的图形化建模,参数设置修改直观方便,而且创建方法简单易行、可扩充性强,不仅为自抗扰控制技术的仿真研究提供了有效工具,并且对相关领域的仿真模型库扩建具有参考价值。Based on studying Active-Disturbance-Rejection-Control （ADRC） technology, a user-defined ADRC Block library was created in accordance with the modular modeling method in MATLAB / SIMULINK, by the way of developing MATLAB function files for special nonlinear functions, designing system functions （S_function） for dynamic algorithms sach as Tracking-Differntiator （TD） and Extened-State-Observer（ESO）, and masking some user defined subsystems for Control Law （CL） combination and ADRC algorithms which often are used. The simulation example of cascade speed control system with ADRC shows that the ADRC simulation model can be built in graphic modeling method, and the block parameters are easy to modify by using custom model library of ADRC technique. Furthermore, the way to create new ADRC block library is simple and the library is easy to be extended. It is a useful tool for searching and simulation of ADRC technology and has a reference value for the expansion of simulation model library in related fields.
