Research on Predefined Time Sliding Mode Control Method for High-Speed Maglev Train Based on Finite Time Disturbance Observer
Published 2025-01-01“…Aiming at the stator current control problem of long-stator linear synchronous motors under parametric perturbation, this paper investigates the double-feeding mode, combines the predefined-time stability theory and designs an improved sliding mode controller to optimise the dynamic characteristics of the inner-loop system. In the outer-loop cruise control, the predefined-time sliding mode control is combined with a finite-time disturbance observer, which effectively solves the problems of inaccurate modelling and parameter ingestion. …”

A Comparison between Two Force-Position Controllers with Gravity Compensation Simulated on a Humanoid Arm
Published 2013-01-01“…The two controllers are both constituted by an internal proportional-derivative (PD) closed-loop for the position control. The force control of the two systems is composed of an external proportional (P) closed-loop for one system (P system) and an external proportional-integrative (PI) closed-loop for the other system (PI system). …”

Stress tunable spin dynamics of a magnetic vortex under resonant magnetic fields
Published 2025-01-01“…Specifically, tensile stress induces a buckling state, facilitating the transition from the parallel spin to the vortex state in smaller disks and introducing a distinct kink in the hysteresis loop. Conversely, compressive stress causes the disappearance of the original intermediate state in larger disks, leading to a smoother hysteresis loop. …”
