Part VI: MIMO Control Essentials
In this part of the book we turn to systems having multiple inputs and/or multiple outputs. Of course most (if not all) systems met in practice will be of this type. Fortunately, it is frequently the case that the inputs and outputs can be grouped into pairs and treated as if they were separate single-input single-output (SISO) problems. Indeed, this is why we have treated SISO control loops in such detail in earlier parts of the book. However, in other cases, non-negligible interactions between the multiple inputs and outputs can occur. In this case, one really has no option but to tackle control design as a genuine multiple-input multi-output (MIMO) problem. This is the topic of this part of the book.
