DOI: 10.1002/asjc.2278
Abstract: The output feedback control issue is addressed for a class of non‐affine nonlinear systems in this paper. In the situation that the internal states of the system are not available, we design a neural network… read more here.

Abstract: Dutch roll motion is a type of aircraft lateral/directional oscillation, and its control problem has two main challenges. First, a multiple-input–multiple-output (MIMO) non-affine Dutch roll dynamics may result in nonzero equilibriums and unstable oscillations due… read more here.

DOI: 10.1007/s11071-020-05536-3
Abstract: This paper mainly addresses the finite-time tracking problem of pure-feedback systems with indifferentiable non-affine functions. A novel adaptive fuzzy finite-time command filtered scheme is proposed by remodeling the non-affine functions. The control scheme consists of… read more here.

DOI: 10.1007/s40313-020-00580-1
Abstract: In this paper, two techniques are introduced to transform an uncertain second-order non-affine system under input saturation to an equivalent affine model. First, this affine model is obtained using the linearization technique with respect to… read more here.

Abstract: Abstract This paper investigates a prescribed performance control strategy for air-breathing hypersonic vehicles (AHVs) based on neural approximation. Different from the existing studies, the explored controllers are derived from non-affine models instead of affine ones.… read more here.

DOI: 10.1016/j.ifacol.2019.09.121
Abstract: Abstract This paper deals with the stabilization problem for single-input-single-output (SISO) non-affine-in-control nonlinear discrete-time systems. Generally, this non-affine-in-control problem leads to algebraic loops and a classical solution consists in using dynamic extensions. Based on Takagi-Sugeno… read more here.

DOI: 10.1016/j.jmps.2021.104576
Abstract: Abstract There has been increasing experimental evidence of non-affine elastic deformation mechanisms in biological soft tissues. These observations call for novel constitutive models which are able to describe the dominant underlying micro-structural kinematic aspects, in… read more here.

Abstract: When an amorphous solid is deformed homogeneously, it exhibits heterogeneous plastic instabilities with a localized cooperative rearrangement of a cluster of particles in response. The heterogeneous behavior plays an important role in deciding the mechanical… read more here.
