What Are LTIs? Linearizing Systems Made Easy with MATLAB and Simulink

Linear time-invariant systems (LTIs) are exactly what you would think they are: systems that are linear and time-invariant. Linear time-invariant systems are some of the easier systems to model because the inputs and outputs have a linear relationship that doesn’t vary based on the input that is given. However, very few systems are naturally linear and time-invariant; with MATLAB^® and Simulink^®, you can create linear representations of your system to aid in control design.
