Interval Switched Positive Observers for Discrete-Time Switched Positive Systems under Arbitrary Switching

In this paper, we consider the two types of interval switched positive observers for discrete-time arbitrary switched positive linear systems under the assumption that the initial state of the switched system is between known lower and upper bounds. Firstly, the interval full-order switched positive observers for discrete-time switched positive linear systems are studied. Next, the interval reduced-order switched positive observers for the same switched positive linear systems are studied. Finally, an illustrative numerical example is shown.
