Sliding Mode Observers for Distributed Parameter Systems: Theory and Applications
… it is not always possible to have access to the states of the systems due to technical difficulties such as lack of sensors. Therefore, there is the need for state observers to estimate the states of the system only having the output of the system available. In this research, the theory of …

A Koopman-Based Reduced-Order State Observer for Visual Localization of Robots
… in general; standard Kalman filter and state observers cannot be applied to such non-observable systems. The other is that a large number of observables are required for accurate linearization. Here, we present 1) a new reduced-order state observer for a Koopman lifted linear model that …

Nonlinear observer design and synchronization analysis for classical models of neural oscillators
… nonlinear systems were used to develop a set of observers and perform synchronization analysis on the aforementioned neural systems. By using matrix analysis techniques, a study of biological background and motivation, and MATLAB simulation with mathematical computation, it was possible to do a …

Decentralized thermal control of building systems
… It entails the use of decentralized extended state observers to address the issue of unavailability of unknown states and disturbances in the system. The potential use of the proposed control architecture selection and decentralized control design methodologies is demonstrated in simulation on …

On Observer-Based Control of Nonlinear Systems
… are based on the assumption that all internal states of the control object are available for feedback. In most cases, however, only a few of the states or some functions of the states can be measured. This circumstance raises the need for techniques, which makes it possible not only to estimate …

Modeling, Design, Identification, Drive, and Control of a Rotary Actuator with Magnetic Restoration
… nonlinear control with feedback linearization. State observers are employed to estimate the unmeasured states. The control techniques are evaluated and compared through time response indices such as rise time, overshoot, steady-state error, and large-signal tracking, as well as by frequency …

Sensing Atmospheric Winds from Quadrotor Motion
… from 0 to 2 m/s in intervals of 0.5~m/s. State observers for wind profiling were synthesized using all five rigid body models. Performance assessments employing wind observations from in situ and remote sensors demonstrated model-based wind profiling results to be be in close agreement …

Performance index analysis of control systems synthesized for a counter-current process
… developed to enable this type of analysis on state-space control systems with state observers. The package enables the synthesis of LQG optimal control systems and the quantitative assessment of the ability of such systems to meet their design objectives. A package has been developed to run …
