· Basically a system will become unstable if a transfer function starts to grow. We can predict this by looking at the characteristic equations.
· The characteristic equation is the denominator of the transfer function.
· If any of the roots of the equation are less than one, then the system can become unstable, and most likely will.
· Determine if the function below is stable, if y is the output,
