Event-Triggered Filter of Switched Positive Systems with State Saturation

This paper investigates the event-triggered filter of switched positive systems subject to state saturation. First, a filter is constructed for switched positive systems. An error system is obtained by combining the switched systems and the filter. Under the event-triggering condition, the error system is transformed into an interval system. Linear programming is employed to design the gain matrices of the filter. Accordingly, the positivity and stability of the error system are guaranteed by virtue of the corresponding issues of the interval system. A cone based domain of attraction is constructed for the invariant property of the system. Finally, an example is proposed to verify the validity of the theoretical findings.
