A novel finite-time control with q-axis current constrained based on time-varying second-
order nonlinear disturbance observer is investigated to improve the performance of …

Servo drives require high dynamics and reliability on speed control. Conventional cascade
linear controllers suffer from the proportional-integral parameters tuning work and low …

This article proposes neural network (NN) based observer schemes and a sensorless robust
optimal control scheme for partially unknown permanent magnet synchronous motors with …

Several advantages are provided by the permanent magnet synchronous motor (PMSM)
over DC motors and is gradually replacing them in industry. The dynamics of the PMSM can …

Due to high power density, high efficiency, and accurate control performance, permanent
magnet synchronous motors (PMSMs) have been widely adopted in equipment …

This article presents a two-degree-of-freedom (2DOF) H speed control structure for
permanent magnet synchronous motors (PMSMs). This structure consists of three parts: an …

The current constraint and robustness improvement of the speed-current single-loop
controlled permanent magnet synchronous motor (PMSM) are investigated. To begin with, a …

This article proposes a novel optimal tracking control scheme for permanent magnet
synchronous motors (PMSMs) with partially unknown dynamics, saturation voltages, and …

Motors that convert electrical energy to mechanical energy, have been considered as one of
the most crucial components of all-climatic electric vehicles (EVs). In order to realize high …

The dynamics of the permanent magnet synchronous motor (PMSM) are described by
nonlinear equations, which present challenges. Variations in external factors such as …
