Emphasis is placed on the necessity for geometric optimization of an interface in order to design singularity-free junction with higher interfacial strength.
This is carried out by considering a beam type specimen which presents design singularities such as important thicknesses, ply drop off zones and a reinforced zone.
The focus of this paper is the problems associated with elimination of the stress singularities, with the goal of providing an approach for designing singularity-free bi-material joints.
The scheme integrates fuzzy logic systems, state observers, and strictly positive real conditions to deal with three issues in the control of a large-scale MIMO uncertain nonlinear system: algorithm design, controller singularity, and transient response.
A method to design a singularity-free 3-arm planar parallel mechanism is presented.
Within the design space, the singularity, usable workspace and control accuracy (evaluated using the GCI) are studied and the corresponding atlases are constructed.
A new steering law is designed based on singularity value decomposition theory.
State feedback controllers are designed to eliminate singularity induced bifurcation and stabilize the proposed system around corresponding interior equilibrium.
"The explosion of complexity" occurred in the traditional backstepping technique has been avoided utilizing the dynamic surface control (DSC) technique and the designed controller is singularity free.
Then, a fuzzy controller is designed that solves the singularity problem through regulation of a design parameter in the control law.
And while that means more success in business, it does not necessarily encourage more singularity in design and embellishment.
