一类多生产线可重入制造系统的层次化鲁棒控制策略
A hierarchial robust control strategy for multi-line re-entrant manufacturing systems
摘要
Abstract
This article investigates the hierarchical intelligent control strategy for a class of multi-lines re-entrant man-ufacturing systems.Based on the hierarchical modeling technique,a hyperbolic partial differential equation(PDE)is employed to express the overall complex system behaviors and a corresponding robust controller is constructed such that the manufacturing systems enter an expected steady working mode in finite time.With the combination of the fuzzy mod-eling technique and sliding control approach,the closed-loop manufacturing plants can suppress the inevitable disturbances in the sense of H∞ performance.Due to the inherent infinite-dimension nature of the designed control synthesis,an effec-tive numerical algorithm is proposed to solve the controller design via the convex optimization technique.The provided numerical experiments demonstrate the feasibility and advantages of the proposed intelligent control strategy.关键词
