In Figure 11.2, the controller has input and output , resulting in a 1x1 transfer function for . The (generalized) process dynamics has outputs and and inputs and . So the proper dimension of the matrix transfer function is 5 x 3.
The updated text should read
If we omit the reference input , the system in Figure 11.1 can be captured by choosing and . The process transfer function is a 5 x 3 matrix, and the controller transfer function is a 1 x 1 matrix; compare with Exercise 11.3.
