In the paper, the authors present a method for stabilising uncertain time-delay systems. The systems under consideration are described by linear state delayed equations whose coefficient matrices contain norm-bounded time-varying elements. Using some

This paper presents the analytical and experimental consideration of the common-mode noise generation in a single-switch (buck) converter comparison to a four-switch (full-bridge) converter by the viewpoint of circuit imbalance. The mechanism of the

General switching converter such as the simple high-side switching circuit inherently has unbalanced characteristics of impedance of transmission path, voltage at dc source and load terminals with respect to the frame ground. These unbalanced charact

A servo motor driving a load through a long shaft or transmission system is widely used in industries. Such a system encounters performance degradation caused by non-homogeneous twist of the shaft. This phenomenon is referred to as torsional resonanc

A technique is presented for contactless angular speed measurement of two-phase AC servomotors. It is based on the measurement of the counter EMF of the motor, by balancing the voltage supplied to the motor by an amplifier against the counter EMF gen
