A Simple Feedback Controller to Reduce Angular Momentum in ZMP-Based Gaits

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

A simple approach to the angular momentum distribution in the ground states of many-body systems

We propose a simple approach to predict the angular momentum I ground state (Ig.s.) probabilities of many-body systems that does not require the diagonalization of hamiltonians with random interactions. This method is found to be applicable to all cases that have been discussed: even and odd fermion systems (both in single-j and many-j shells), and boson (both sd and sdg) systems. A simple rela...

Angular Momentum in Chemistry

Noting that current chemical theory is based almost exclusively on electronic energy and spin variables the equal importance of orbital angular momentum is explored in this paper. From its classical definition the angular momentum of electrons in an atom is shown to obey Laplace’s equation, which automatically leads to discrete values in terms of spherical harmonics. This analysis assumes a con...

A simple adaptive-feedback controller for high-quality chaos synchronization

Based on the invariance principle of differential equations, a simple uniform coupling scheme is proposed to strictly synchronize almost all chaotic systems. Namely, one may synchronize highqualitatively chaotic systems by the uniform adaptive-feedback controller, i.e., a simple feedback coupling with the updated feedback strength. Unlike the usual linear feedback, the variable feedback strengt...
