This article studies the event-triggered model-free adaptive control (ET-MFAC) problem for a class of nonlinear cyber-physical systems (CPSs) in the case of false data injection (FDI) attacks. The nonlinear CPSs are transformed into an equivalent linear data model, in which the nonlinear characteristics of the system are compressed into a pseudo partial derivative parameter. Then, a novel ET-MFAC framework under FDI attacks is established and the event-triggered mechanism is designed to save the communication resources. Based on the designed ET-MFAC framework with FDI attacks, a new ET-MFAC algorithm is developed to track the reference trajectory under FDI attacks. The developed control algorithm only depends on the input and output data of the system and has nothing to do with the structure of the system, which makes the result with good robustness. Finally, a simulation is given to illustrate the validity of the developed ET-MFAC algorithm. [ABSTRACT FROM AUTHOR]

Very often, outsourced components (known as standard components) are used for reducing design effort and product cost in mould design. They are usually manufactured by specialised suppliers. 3D CAD parametric models of these components will significantly reduce mould design lead-time and cost, and enhance design flexibility. This paper presents the detailed object definition, design, and implementation of a Standard Component Library within a mould design software package, QuickMould. With many components from different suppliers implemented, it is believed that the object design has generic nature and can be expanded to include most mechanical components in a collaborative environment. The advantages of this implementation are the compressed data structure, the ease of use and simple customisation. [ABSTRACT FROM AUTHOR]
