摘　　要：研究一类线性不确定网络化系统信息受限情况下的模型控制问题.在被控系统和模型系统通过带宽受限网络相连的情况下给出了有效的量化方法,使得量化值能够在量化器的容许范围之内,并给出了系统在一定条件下渐近稳定的充分条件.最后的仿真算例表明了所提出方法的可行性.This paper studies the model-based control problem for a class of linear uncertain networked systems with limited information.The uncertain controlled plant and its minimized system as a model plant are connected via a communication network with limited bandwidth.In this case,an effective quantization algorithm is presented such that quantization value can be measured adequately.A sufficient condition for a globally asymptotical stabilization under some certain conditions is obtained.Finally,a simulation example shows the effectiveness of the proposed method.
