Nonlinear observers for autonomous Lipschitz continuous systems
This paper considers the state observation problem for autonomous nonlinear systems. An observation mapping is introduced, which is defined by applying a linear integral operator (rather than a differential operator) to the output of the system. It is shown that this observation mapping is well suited to capture the observability nature of smooth as well as nonsmooth systems, and to construct o...
متن کاملStochastic Nonlinear Observers for Industrial Seeded Batch Crystallization Processes
A substantial amount of materials in the pharmaceutical, food, and fine chemical industry is produced in crystalline form. Batch crystallization is a key separation and purification unit in such industries, with a significant impact on the efficiency and profitability of the overall process. Advanced model-based control of crystallization processes offers many possibilities to achieve the strin...
متن کاملOscillatory Behavior Control in Continuous Fermentation Processes
The continuous fermentation processes involving yeast Saccharomyces cerevisiae or bacterium Zymomonas mobilis often exhibit oscillatory behavior. Because, the oscillatory mode of operation may lead to higher or lower average ethanol concentrations, hence, there is a natural need to control this behavior. The idea presented in this paper is based on the use of a mixture of two substrates that ar...
متن کاملNonlinear Observers
This paper is a review of the existing methods for designing an observer for a system modeled by 18 nonlinear equations. We focus our attention on autonomous, finite dimensional systems described 19 by ordinary differential equations. The current condition of such a system is described by its state 20 variables about which we just have partial and possibly noisy measurements. The goal of the 21...
متن کاملError models for nonlinear observers
We revisit the concept of observation error for nonlinear observers of nonlinear systems. In order to obtain a coordinate free notion of such an error we define it using fiber bundles over the system manifold. The new notion ties in nicely with Brockett’s and Willems’ classical description of nonlinear systems as bundles as well as with the related description of observers as bundles due to van...
