This article presents the fast convergent stability of disturbance observer (DO) and sliding
mode control (SMC) for a secure communication of fractional-order chaotic-based system …

The slotless self-bearing motor (SSBM) is a motor with its self-bearing function. The
mechanical structure of the motor is six symmetrical hexagonal shapes. The main control …

In this paper, sensorless robust speed control with nonlinear lumped mismatched
disturbance observers for a permanent magnet type axial gap bearingless motor (AGBM) is …

To prevent the loss of data or distortion of the real sent data in the secure communication,
the disturbance and uncertainty rejection is very important technique. Especially, the secure …

This paper proposes a fixed-time stability (FTS) disturbance observer based-on an adaptive
sliding mode control for the secure communication of chaos-based system. Firstly, the …

This paper proposes a new fixed-time disturbance observer (FTDOB) based on the fractional-
order state observer (FOSOB) and a super-twisting sliding-mode control (STSMC) for a …

This paper presents a robust adaptive boundary layer thickness (BLT) of sliding mode
control (SMC) for a secure communication of chaos-based system. First, chaotic system was …

A slotless self-bearing motor (SSBM) is a new type of electric motor, with its levitating and
rotating capability as a drive system. In the design of motor, the iron core of stator was …

As well known, the fabrication error of winding process, uncertainty of thermal changing, and
disturbance from outside of the system are some inversed factors for a motor control system …

Active Magnetic Bearings (AMBs) use magnetic forces to suspend the rotor, allowing
contactless operation and the ability to adjust stiffness and damping. However, compared to …
