| 中文摘要 |
| 本文针对一阶线性时不变(FOLTI)系统, 将常用的比例–积分–微分(PID)控制器参数整定方法推广到无模型自适应控制(MFAC)参数整定中, 利用PID控制参数整定方法整定直接型MFAC方案的伪梯度初值, 以期改变MFAC控制律初始参数的试凑式选取, 提升MFAC应用的方便性和可接受性. 通过仿真, 验证了所提伪梯度初值整定方法的有效性, 并对比了FOLTI系统的系统参数和系统结构发生变化后, 应用MFAC与PID控制的性能差异. |
| 英文摘要 |
| For the first-order linear time-invariant (FOLTI) systems, several classic proportional-integral-derivative control (PID) controller parameter tuning methods are introduced for the initial values tuning of the pseudo gradient (PG) in the model-free adaptive control (MFAC) scheme which will change the current situation of trial-and-error selection of the initial MFAC parameters for improving the convenience and acceptability of MFAC application. Finally, numerical simulations verify the effectiveness of the proposed PG initial value tuning method and demonstrate the performance difference between MFAC and PID control when the system parameters and structure of FOLTI systems are changed. |
