Introduction
[edit | edit source]Wile in the case of autonomous systems, they only need initial input constraints and cannot be changed using external inputs; the non-autonomous systems on the other hand can have changes happen to its behavior using a controller.
The System
[edit | edit source]Consider the continuous-time LTI system with state space realization
The Data
[edit | edit source], , , &
Determining the bound
[edit | edit source]The output of this system must satisfy
if there exists some matrix and scalar ,
where
,
such that
,
.
Implementation
[edit | edit source]This can be implemented in any LMI solver such as YALMIP, using an algorithmic solver like Gurobi.
Conclusion
[edit | edit source]Given a non-autonomous system with initial operating conditions and a controller, the parameter can be used to determine the feasible bound on the output of that system.
