The shape memory alloy (SMA)-based robotic hand has been a new emerging technology with potential applications ranging from life service to surgical treatment, because of the characteristics SMA, such as high power-to-weight ratio, small volume and low driving voltage. However, due complex dynamic model nonlinear aspects it is complicated control an SMA-based hand. This paper presents novel fre...

A novel pure penalty discontinuous Galerkin method is proposed for the geometrically nonlinear analysis of multilayered composite plates and shells, modelled via high-order refined theories. The approach allows to build different two-dimensional equivalent single layer structural models, which are obtained by expressing covariant components displacement field through-the-thickness Taylor’s poly...

This paper deals with the use of extra freedom in the exact linearization technique. Firstly, the freedom in choosing the coordinate transformation and nonlinear state feedback for the exact linearization is clarified. Secondly, a controller design strategy for the transient behavior improvement in the presence of impulsive disturbances is shown. Finally, numerical and experimental examples exh...

The current article is concerned with a comprehensive investigation of achieving the simplest solution non-conservative coupled nonlinear forced oscillators. mainly depends on non-perturbative method. It yielding an equivalent linear system. advantage this system that its coefficients are easily computed and they include effects original coefficients. This linearization approach allows quasi-ex...

A simple interval method is suggested for globally solving optimization problems of the following type: minimize the objective function φo(x) subject to the functional constraints φo(x) ≤ 0, i=1,...r and the boundary constraints x∈ X(o) where x is a n-dimensional vector and X(o) is a given initial search region (a box). All the functions involved are assumed continuously differentiable in X(o)....

In 2007 PKC conference, Ding, et al use the second order linearization equation attack method to break what be called MFE multivariate public key encryption scheme, and also proposed a high order linearization equation attack on multivariate public key cryptosystems. To resist high order linearization equation attack, we present an enhanced MFE encryption scheme in this article. The improved sc...

In this paper, we develop a method to design the input control to track the output of a nonminimum-phase nonlinear systems asymptotically. The design of the control inputs is based on an exact linearization. To perform the exact linearization, the other output should be selected such that its relative degree is equal to the dimension of the system. Furthermore, the desired output of the output ...
