Abstract :
Input and state estimation of a dynamic system can find many applications in fault detection and diagnosis, target tracking, and so on. This paper presents a new simultaneous input and state estimation scheme. A recursive algorithm is developed based on the idea of achieving minimum mean square error and minimum error variance. The convergence property of the proposed algorithm is also analyzed. Numerical examples are provided to illustrate the effectiveness of the algorithm.
