Continuous-Time Systems
2.1 INTRODUCTION
Before we start our exploration of simulation, it is important for us to have some basic knowledge of
how linear time-invariant (LTI) dynamic systems behave. The analysis of linear systems and how
they respond to elementary types of inputs is straightforward. Linear systems appear as building
blocks in more complex systems. Our intuitive understanding of the entire system is enhanced by
recognizing the fundamental behavior of its linear components. Control systems, for example, are
oftentimes composed of linear continuous-time components interconnected to produce a desirable
response to commanded as well as ...
