This paper studies the impact of adding additional control channels to a square discrete-time MIMO plant. Our aim is to quantify the performance gains and therefore, to determine whether this benefit, compared to the cost associated to the channels implementation and maintenance, is such as to justify the additional channels. We first analyse the impact on the non-minimum phase zeros (including zeros at infinity) when we add input channels. Then, we compute the associated change on the best… CONTINUE READING
