Five-phase induction motors have the characteristics of high torque density, low ripple, and flexible control, making them suitable for medium- low-voltage power supply situations. However, with expansion application scenarios, five-phase need to cope increasingly complex operating conditions. propeller propulsion will face various sea conditions during actual use, electric vehicles also road r...

Abstract Two different DC offset compensators for sensorless PMSM, motor drives with wide speed range flux linkage observers, are introduced and compared. The first one is an improved observer PI correction no need mover phase adaptation. second a novel active disturbance rejection controller (ADRC) compensator without ESO built into ADRC able to detect compensate both internal model external l...

In an interconnected power system, as a power load demand varies randomly, both area frequency and tie-line power interchange also vary. The objectives of load frequency control (LFC) are to minimize the transient deviations in theses variables (area frequency and tie-line power interchange) and to ensure their steady state errors to be zeros. When dealing with the LFC problem of power systems,...

The problem of quadrotor attitude and position control is considered in the presence generally lumped disturbances: external disturbances model uncertainty. improved active disturbance rejection controller (ADRC) for trajectory tracking proposed compensating disturbances. Firstly, sigmoid differentiator (ISTD), combining Sigmoid function sliding mode terminal attractor proposed, which can accel...

In the proposed paper, we have presented the need for Load Frequency Control (LFC) of an interconnected multi-area power to minimize the transient deviations in area frequency and tie-line power interchange and to ensure their steady state errors are zeros. In this paper, the Load Frequency Control achieved by implementation of one of the following conventional controller strategies: Proportion...

For grid-connected DFIG-based wind turbine, Fault Ride Through (FRT) or Low Voltage (LVRT) capability is vital problem that need to be improved. This paper proposes an Active Disturbance Rejection Control (ADRC) strategy applied Doubly Fed Induction Generator (DFIG) based Wind turbine (WT), which integrates a Dynamic Restorer (DVR). The DVR connect in series the DFIG output terminal and utility...

One main contribution of this dissertation is to analyze the stability characteristics of extended state observer (ESO) and active disturbance rejection control (ADRC). In particular, asymptotic stability of the dynamic system that describes the estimation error and the closed-loop system is established where the plant dynamics is completely known. In the face of large dynamic uncertainties, th...

High-speed and high-precision position servo system of permanent magnet synchronous motor (PMSM) is the key part research development manipulator's joint. The active disturbance rejection control (ADRC) one commonly used methods in system, which has advantages fast speed easy physical realization. However, existing ADRC mostly adopts three-loop structure position-speed-current, some problems su...

The latest research on disturbance rejection mechanisms has shown active control (ADRC) to be an effective controller for uncertainties and nonlinear dynamics embedded in systems controlled. significance of the ADRC is its model-free nature, as it requires minimal knowledge system model. In addition, can actively estimate compensate impact internal external disturbances present, with aid crucia...

In lower-limb rehabilitation systems, exoskeleton robots are one of the most important components. These help patients to execute repetitive exercises under guidance physiotherapists. Recently, pneumatic artificial muscles (PAM), a kind actuator that acts similarly human muscles, have been chosen power robot for better human–machine interaction. order enhance performance PAM-based robot, this a...
