Due to the influencing factors, such as irregularity of guide, piston wind excitation in the
hoistway, and uncertain swinging of hoisting rope during the operation of high-speed …

This paper mainly analyzes a class of piecewise nonlinear systems with fractional
differential delay feedback control. The average method is used to solve the nonlinear …

In this article, a magnetic suspension technique was introduced into the field of vibration
absorption. Using the advantage of adjustable control parameters of a magnetic suspension …

Magnetorquers are a very suitable solution for the nanosatellite's attitude and orbital control
of low Earth orbit (LEO) given its constraints: small available volume, limited power …

Using magnetic levitation technology to implement a reference signal can avoid fluid
mechanical surge and better control the movement of motorized spindle-mounted cutting …

The design of the magnetorquer is shown in Fig. 1. It consists of an inner cylindrical
ferromagnetic core, fully winded with several overlapped layers of copper wire. The …
