Extension Controller Design via Sliding Mode Control

Chen Jenyang,Wong Chingchang

Strategic Study of CAE 2001, Volume 3, Issue 9, Pages 48-51

Abstract:

In this paper, a novel extension controller based on the scheme of sliding mode control is investigatedOne part is the equivalent control of sliding mode control.By integrating the essential concept of extension set theory with the sliding mode control , the robustThe extension dependent functions are employed to provide system states´ information under controlA set of parameter is incorporated in the extension controller so that a robust control, also called

Adaptive Extension Controller Design for Nonlinear Systems

Wong Qingchang,Chen Zhenyuan

Strategic Study of CAE 2001, Volume 3, Issue 7, Pages 54-58

Abstract:

A design method for the extension controller is developed in this paper.The proposed adaptive extension control resulting from the direct adaptive approach is employed to directlyadapt the gain parameter of the extension controller.Then the constructed controller can be best approximated to a given optimal control.In addition, a maximum control is established to guarantee the system robust stability.

Correlation between tension softening relation and crack extension resistance in concrete

Xiufang ZHANG , Shilang XU ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3, Pages 323-329 doi: 10.1007/s11709-009-0041-2

Abstract: Changes of the material fracture energy consumption with crack propagation can be described by a crack extensionThe variation of the crack extension resistance is mainly associated with the energy consumption in theThe crack extension resistance is then a function of the softening curve, which is a basic mechanicalThe relationship between the softening curve and the crack extension resistance curve is then analyzedThe results indicate that the characteristic points of the crack extension resistance curve is closely
