A key reasons for computing poles is due to the strong link with system behaviours and in particular stability. This video looks at simple, back of the envelope calculuations that can be used to determine whether the roots are all in the LHP, or not.

Gives a number of tutorial examples for students to attempt before going through the worked solutions. Questions cover factorisation and assessing whether any roots are in the RHP. Also illustrates how MATLAB can be used both to validate your own working and also to determine roots when the...
