Quadratic boundedness is adopted to construct state observers for linear, piecewise linear, and Lipschitz nonlinear systems subject to bounded disturbances. Upp ...

The state estimation for linear discrete-time systems with non-Gaussian state and output noise is a challenging problem. In this paper, we derive the suboptimal quadratic estimate of the state by ...
