Time-invariant systems are systems where the output does not depend on when an input was applied. For example, a power supply whose internal resistance slowly increases as its components degrade is not perfectly time-invariant, as its output for a given input would be different a year later. The system to be controlled is called a 4. After a short introduction to the required Matlab commands linear and time-invariant (LTI) Matlab models are introduced and examples given.
