Frequency Domain Analysis Of The Quadruple Tank System<br>
<br>

<strong>Abstract</strong><br>
Multivariable systems exhibit complex dynamics because of the interactions between inputs and outputs. The 
quadruple-tank process has been widely used for control education to present many concepts in multivariable control, such 
as performance limitations due to multivariable right half-plane zeros or input-output pairing problems. This paper discusses 
the frequency dependent relative gain array, relative gain array number and Nyquist array plots for  the quadruple tank 
system and addresses diagonal dominance and pole assignment problems.
