Function fhan() and tracking differentiator are important components of Active Disturbance Rejection Control Technique. It is pointed out that function fhan() is not the optimal control synthesis function of discrete system, but function fsun() is. Amplitude and phase frequency characteristic curves of tracking differentiators constructed respectively by function fhan() and fsun() are given by computer simulations. The account formula about turning frequency is also given. Influence of parameter variation on tracking differentiator frequency characteristic is analyszed. The conclusion of this paper is supplement and perfection for the theory of tracking differentiator in Active Disturbance Rejection Control Technique, and it can promote rapid development of Active Disturbance Rejection Control Technique.

Attitude Controller

This paper investigates the design problem of the attitude controller for air-breathing supersonic vehicle subject to uncertainties and disturbances. Firstly, the longitudinal model is established for the attitude controller design which is devised as a strict feedback formulation, and a transformed tracking error is derived with the prescribed performance control technique such that it can limit the tracking error to a predefined region. Then, a novel linear active disturbance rejection control scheme is proposed for the attitude system to enhance the steady-state and transient-state performances by incorporating the transformed tracking error. On the basis of the Lyapunov stability theorem, the convergence and stability characteristics are both rigorously proved for the closed-loop system. Finally, extensive contrast simulations are conducted to demonstrate the effectiveness, robustness, and advantage of the proposed control strategy.

Optimizing Control

This paper studies the ADRC(Active Disturbance Rejection Control) technique further used in Permanent Magnet Synchronous Motor. Combining the ADRC with the self-optimizing technique, we design a controller with Self-optimizing Control. The result of simulation shows that the ADRC technique with Self-optimizing Control has better control characteristics, compared with the classical PID and ADRC techniques.

Disturbance Rejection Control

In this paper, new technology of noncircular turning was presented, a voice coil motor-driven fasting tool servo system was established. A dual stage actuator mechanism was designed for the variable rake angle tool in noncircular turning process. The kinematics of mechanism was analyzed. An active disturbance rejection control technique was applied in mechanism control. The tool feeding and the workpiece rotation synchronized by using time-base method of PMAC and achieved the noncircular auto turning. The result shows that it can improve the precision and efficiency of noncircular turning based on active disturbance rejection control.
