Multi Observer Structure for Rapid State Estimation in Linear Time Varying Systems
- 11 Downloads
A new method to design observers for linear time-varying systems is presented in this paper. The method begins by constructing two layers. The first layer is made up of multiple observers, while the second establishes a relationship between observers via a weighted estimation state. The primary challenge was to find a new feedback process that would determine the second layer weights. The multiple observers of the first layer were investigated to determine a general observation law. The resulting multilayer structure significantly improves the transient characteristics of the observation process, which leads to a more efficient control system.
