Active disturbance rejection attitude control for a hypersonic reentry vehicle with actuator saturation

Fuzzy Active Disturbance Rejection Attitude Control of Spacecraft with Unknown Disturbance and Parametric Uncertainty

Based on active disturbance rejection control (ADRC) and fuzzy logic control, a control scheme for attitude maneuver control of spacecraft is proposed. In which a maneuver path is planned to reduce overshoot and improve rapidity, and an extended state observer is designed to cope with unknown disturbances and parameter uncertainties. Furthermore, in order to improve dynamic performance of the c...

Control Study of Precision Giant Magnetostrictive Actuator Based on Active Disturbance Rejection Control Technology

Introduce the structure and working principle of precision giant magnetostrictive actuator and establish the actuator system object transfer function model so as to design a suitable active disturbance rejection controller (ADRC). According to the model analysis, regard the actuator system as a first-order inertia object with dead time to construct second-order ADRC, use MATLAB for parameter tu...

Fault Accommodation for near Space Hypersonic Vehicle with Actuator Fault

Based on fuzzy control and sliding mode observer technique, a fault accommodation strategy is proposed for near space hypersonic vehicle (NSHV) with actuator fault in this study. Firstly, the Takagi-Sugeno (T-S) fuzzy model is implemented to represent the NSHV nonlinear dynamics, and a bank of sliding mode observers are designed for the established T-S model, which are used to generate the resi...

A Disturbance Rejection Approach to Actuator andSensor

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control

Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent.  This controller is used in a double loop structure including an inner current loop and oute...
