LMIs in Control/H2Optimalobserver

State observer is a system that provides estimates of internal states of a given real system, from measurements of the inputs and outputs of the real system.The goal of -optimal state estimation is to design an observer that minimizes the norm of the closed-loop transfer matrix from w to z. Kalman filter is a form of Optimal Observer. The System Consider the continuous-time generalized plant with state-space realization The Data The matrices needed as input are . The Optimization Problem The task is to design an observer of the following form: The LMI: Optimal Observer LMIs in the variables are given by: Conclusion: The -optimal observer gain is recovered by and the norm of T(s) is Implementation https://github.com/Ricky-10/coding107/blob/master/H2%20Optimal%20Observer External Links A list of references documenting and validating the LMI.
