摘要
针对自抗扰控制器参数较多、整定困难的问题,提出基于控制系统性能评价的自抗扰控制器参数整定方法.通过闭环系统的扰动-输出传函求解基准函数,对决定自抗扰控制器性能的参数进行优化.实验结果表明,该参数整定方法简单易行,在满足系统性能最优的前提下,能有效提高ADRC的控制效果.
Considering the problem that the auto disturbance rejection controller （ADRC） has difficulty in setting more parameters, a parameter setting method of ADRC was proposed based on the control performance assessment. The solution of benchmark function was obtained by disturbance-output transfer function of closed-loop system, which was used to optimize the decisive parameters of ADRC. Experimental results show that the proposed parameter setting method can improve the control effect of ADRC and satisfy the system control with optimal performance.
