15. Definitions
System: A combination of components acting together to perform a
specified objective. The components or interacting elements have
cause-and-effect (or input/output) relationships. We will
investigate mechanical, electrical, fluid, and mixed systems.
Dynamic system: The current output variables of a system depend
on the initial conditions (or stored energy) of the system and/or the
previous input variables. The dynamic variables of the system (e.g.,
displacement, velocity, voltage, pressure, etc.) vary with time.
Modeling: The process of applying the appropriate fundamental
physical laws in order to derive mathematical equations that
adequately describe the physics of the engineering system.
16. Definitions
Mathematical models: A mathematical description of a
system’s behavior, usually a set of differential equations for
a dynamic system
Simulation: The process of obtaining the system’s
dynamic response by numerically solving the governing
modeling equations. Simulation involves numerical
integration of the model’s differential equations and is
performed by digital computers and simulation software.
System analysis: The use of analytical calculations or
numerical simulation tools to determine the system
response in order to assess its performance.
