Optimal fast tracking observer bandwidth of the linear extended state observer
International Journal of Control, 2007In current industrial control applications, the proportional + integral + derivative (PID) control is still used as the leading tool, but constructing controller requires precise mathematical model of plant, and tuning the parameters of controllers is not simple to implement.

Extended differential geometric guidance law with extended state observer
2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017No restrictions are imposed on the motion states of missile and target and the line of sight rotation coordinate system is introduced into the derivation of differential geometric guidance law. Then, the extended differential geometric guidance law is achieved whose scope of application is largely extended.

Missile Guidance Law Based on Extended State Observer
IEEE Transactions on Industrial Electronics, 2013The problem of missile interception is investigated in this paper. Sliding-mode controllers with finite-time convergence are proposed for the design of guidance laws. In particular, the control design consists of the estimation of the target acceleration by the extended state observer (ESO), and thus, it achieves the decrease of undesired chattering ...

Extended State Observer for Nonlinear Systems with Uncertainty
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2011Abstract The extended state observer first proposed by Jingqing Han in [J. Q. Han, The extended state observer for a class of uncertain systems, Control and Decision, 10(1)(1995), 85-88] is the main interim loop of active disturbance rejection control that is taking off as a technology after numerous successful applications in engineering ...

Fault Detection of Actuators via Extended State Observer
2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS), 2019This paper focuses on the issue of fault detection of actuators. The proposed fault detection scheme consists of the nominal actuator dynamics and the corresponding modified extended state observer. Simulation of typical autopilot of flight vehicles shows that the proposed method can identify actuator performance degradation from hierarchical ...

A research on state identification and control method based on extended state observer
2018 14th IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA), 2018This paper focuses on the study of the transition control of hypersonic vehicles with two stages of flight. An active disturbance rejection controller with special instruction generation and double-loop extended state observers (ESO) is proposed, which realizes the identification and control of the equilibrium state.

Extended high gain observer design for state and parameter estimation
2015 4th International Conference on Systems and Control (ICSC), 2015This paper investigates the design of an extended high gain observer to estimate the state together with some unknownconstant parameters for a class of nonlinear systems. We firstly consider the case where all the parameters are known. A high gain state observeris proposed and its exponential convergence is carried out under a well defined persistent ...

Hybrid extended Luenberger-asymptotic observer for bioprocess state estimation
2003 European Control Conference (ECC), 2003Abstract State observers generate estimates of non-measured variables based on a mathematical model of the process and some available hardware sensor signals. On the one hand, exponential observers, such as Luenberger observers or Kalman filters, have an adjustable rate of convergence, but strongly rely on the accuracy of the process model.
