Abstract: To solve the problem of the high operational fluctuation for the supply chain nonlinear system caused by uncertain system parameters and uncertain exogenous demand,a robust control approach was researched.Based on the discrete Takagi-Sugeno fuzzy system,a fuzzy model for the uncertain supply chain nonlinear system was developed.By constructing a discrete piecewise Lyapunov function in every maximal overlapped-rules group,a new fuzzy robust H∞ control approach was proposed in terms of the parallel distributed compensation technology.This control approach could not only reduce the number of solving the linear matrix inequalities largely,but also guarantee the robust stability of uncertain supply chain nonlinear system.The effectiveness of proposed approach was demonstrated through the simulation on a class of two-stage uncertain supply chain nonlinear system.
