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 ...

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 ...

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.

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.

An Extended State Observer Based on Tracking Differentiator
2006 Chinese Control Conference, 2006A series tracking differentiator (TD) that is in the form of observer is used as substitute for the extended state observer (ESO) in active disturbance rejection controller (ADRC). This improved ESO independently of original system model is not only simple for the parameters tuning, but also good for filter performance. The simulation results show that

A New Switching Nonlinear Extended State Observer
2019 Chinese Control And Decision Conference (CCDC), 2019To improve the observation accuracy and shorten the transient time simultaneously, in this paper, we propose a new nonlinear extended state observer (ESO) by using a switching strategy. The convergence of the proposed ESO is proved with explicit error estimation. The effectiveness of the proposed switched nonlinear ESO is demonstrated through numerical

Novel Augmented Extended State Observer Design
2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics, 2015This paper proposes the construction method and validation of novel augmented extended state observer (NAESO). First, based on singular perturbation technique, the general formulation and structure of NAESO is derived. Based on which, the linear NAESO version is given. The merits of the presented NAESO include ease of parameter selection and sufficient

A Bi-bandwidth Extended State Observer for System with Measurement Noise
2020 IEEE 16th International Conference on Control & Automation (ICCA), 2020Although traditional Extended State Observer (ESO) can efficiently estimate the total disturbance of the system theoretically, observation may diverge from the actual system when the measurement noises exist, due to the sensibility of such high-gain-observer to noises.

Extended state observer for MIMO nonlinear systems with stochastic uncertainties
International Journal of Control, 2018ABSTRACTIn this paper, both linear extended state observer (ESO) and nonlinear ESO with homogeneous weighted functions are proposed for a class of multi-input multi-output (MIMO) nonlinear systems ...
