Bi‐homogeneous observers for uncertain 1‐DOF mechanical systems

نویسندگان

چکیده

A global, bi-homogeneous, observer for a class of 1-DOF mechanical systems with Coriolis and centrifugal forces, dry viscous frictions non-vanishing bounded uncertainties/perturbations is proposed, ensuring predefined upper bound convergence time. The options acceleration are discussed in simulation example.

Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain Systems

Using Tracking Differentiators in Designing Nonlinear Disturbance Observers for Uncertain SystemsNaser Kazemzadeh, Saeed BarghandanAbstractIn the present paper, a practical designing method has been proposed for a novel class of NDOs based on TD. Such NDOs can nearly estimate all uncertain disturbances (specifically disturbances without prediction information). Regarding the outstanding perform...

This paper deals with the issues of sensor fault detection for a class of Lipschitz uncertain nonlinear system. By definition coordinate transformation matrix for system states and output system, at first the original system divided into two subsystems. the first subsystem includes uncertainties but without any sensor faults and the second subsystem has sensor faults but is free of uncertaintie...

Delay-Dependent Observers for Uncertain Nonlinear Time-Delay Systems

This paper is concerned with the observer design problem for a class of discrete-time uncertain nonlinear systems with time-varying delay. The nonlinearities are assumed to satisfy global Lipschitz conditions which appear in both the state and measurement equations. The uncertainties are assumed to be time-varying but norm-bounded. Two Luenberger-like observers are proposed. One is delay observ...

Interval Observers for Uncertain Nonlinear Systems. Application to Bioreactors

This paper is about state estimation for nonlinear uncertain continuous-time systems in a bounded-error context. We introduce a method for designing a guaranteed interval observer which is based on (i) the application of Müller’s theorem for bracketing the solution of ordinary differential equations in a way which ensures the positivity of the observation error, (ii) the analysis of the monoton...

Dynamic neural network-based robust observers for uncertain nonlinear systems

A dynamic neural network (DNN) based robust observer for uncertain nonlinear systems is developed. The observer structure consists of a DNN to estimate the system dynamics on-line, a dynamic filter to estimate the unmeasurable state and a sliding mode feedback term to account for modeling errors and exogenous disturbances. The observed states are proven to asymptotically converge to the system ...
