A system model can include variables, parameters, equations, functions, diagrams, or graphs that describe the relationships between the input, output, feedback, and control of the system.

<P>The key to a successful application of control theory is modeling. Chapter 2 describes how to model individual components using difference equations, and Chapter 3 details how to analyze these ...

The stability and self-excited oscillations of nonlinear feedback control systems are investigated in the parameter plane with respect to both the system parameters and the initial conditions. The ...
