You can use the feedback and feedforward functions to create the closed-loop transfer functions of your system. You can also use the lsim or the ode45 functions to simulate the time-domain ...

To ensure that your root locus design meets your specifications and works as expected, you should plot the closed-loop transfer function to check its poles, zeros, and stability margins.

This chapter first discusses closed‐loop stability by examining the locations of closed‐loop poles and the applications of the Routh‐Hurwitz stability criterion. It then presents the Nyquist stability ...
