为满足消费者多样性的需求且充分体现实际供应过程中的非线性特性,研究具有时变时延供应链系统的模糊控制器设计问题.首先用一个T-S模糊模型描述所考虑的供应链系统.然后利用Lyapunov方法和平行分布补偿技术,建立能够保证系统渐近稳定且具有干扰抑制水平γ的条件.此外,以线性矩阵不等式(LMIs)的形式给出控制器设计条件.最后通过仿真例子验证控制器设计方法的有效性.

T-S fuzzy controller design for supply chain systems with time-varying delay

In order to satisfy the various consumer demand and reflect effectively the nonlinear characteristic in the process of practice supply.The fuzzy control problem of supply chain systems with time-varying delay is concerned.Firstly, a T-S fuzzy model is used to describe the considered supply chain system.Then, based on the Lyapunov approach and parallel distributed compensation technology, sufficient conditions of asymptotically stable with a disturbance attenuation level γ are established.Furthermore, conditions for controller design are given by the LMIs, which are easily available for resolution.Finally, a numerical example is proposed to illustrate the effectiveness, it shows that under the condition of low inventory, the consumer demand is met by using the controller designed method.
