具有纯滞后的一阶惯性环节是研究滞后问题的典型对象。采用修改后的二阶自抗扰控制器ADRC(Auto Disturbance RejectionController) ,研究了大纯滞后纯积分对象的控制。仿真表明 ,二阶ADRC能有效控制该类对象 ,并表现出较强的鲁棒性和抗扰性 ,而且在一定程度上不存在所谓的模型失配问题。此外 ,给出了滞后时间从 0开始不断增加的控制器参数调整表和基于时间尺度的控制器参数调整依据 ,具有一定的工程实用价值。
The first-order inertia with pure hysteresis is the typical object of the study of hysteresis. A modified second-order ADRC (Auto Disturbance Rejection Controller) is used to study the control of pure integral with large pure lag. The simulation results show that the second-order ADRC can effectively control such objects and show strong robustness and immunity, and to some extent, there is no so-called model mismatch problem. In addition, the controller parameter adjustment table whose hysteresis time is increasing from 0 and the parameter adjustment basis of the controller based on the time scale are given, which has certain engineering practical value.
