AbstractPurpose -The purpose of this paper is to propose a guaranteed cost control design procedure for model-based cyber-physical assembly systems. In order to reflect the cyber-physical environment, the network-induced delays and disturbances are introduced in the mathematical model.Design/methodology/approach -Based on the linear matrix inequality approach, the guaranteed cost controller is designed such that the guaranteed cost can be satisfied and the corresponding convex optimization algorithm is provided. Moreover, H-infinity theory is employed to deal with the disturbance with the given H-infinity attenuation level.Findings -By constructing appropriate Lyapunov-Krasovskii functionals, delaydependent sufficient conditions are established in terms of linear matrix inequalities and the controller design procedure is given.Originality/value -A simplified cyber-physical assembly model is given, based on which the designed controller can allow us to control the closed-loop cyber-physical assembly systems with the guaranteed cost.

An IoT-Based Cyber-Physical Framework for Turbine Assembly Systems

“…Tan et al [24] analyzed the requirements of industrial robot assembly and proposed a four-level decentralized dynamic closed-looped cyber-physical interaction architecture for a shop-floor assembly system to handle the planning and scheduling problem. Liu [25] proposed a guaranteed cost control design procedure for model-based cyber-physical assembly systems, which provides support to control closed-loop assembly systems with a guaranteed cost and responds to disturbances. The effectiveness of the proposed control method is demonstrated by a single-axis servo drive.…”

A novel hybrid control approach for modular automation system: a case study of sensorless interior permanent magnet in-wheel motor

“…A simplified cyber–physical assembly CPA model was given based on which the designed controller can allow us to control the closed-loop CPA systems with the guaranteed cost. (Liu, 2016). A glove-based virtual hand grasping approach for virtual mechanical assembly was discussed to support a virtual hand to assemble mechanical parts (Li et al , 2016).…”
