摘要
在系统具有时滞性和非线性不确定因素的情况下,为保持Smith预估器与被控对象的一致性,运用非线性PI控制器,消除系统中不确定因素的影响。通过仿真试验,证明Smith预估器和非线性PI控制器算法的结合,可以使具有非线性不确定性的时滞系统达到理想的控制目标。
This paper proposes an improved method to control a nonlinear uncertain system with time-delay.In order to maintain the uniformity between the Smith-predictor and the object,a nonlinear PI controller is used to remove the influence of uncertain elements.It is proved that the proposed method can control this special system to attain ideal effects.
