Expert system issues for multivariable control

In this chapter some of the issues related to the off-line design of single-input single-output (SISO) and multiple-input multiple-output (MIMO) control systems are discussed. Particular emphasis has been placed on the issues concerning the transfer of the expertise implicit in control theoretical knowledge into the design environment for general use by industrial design engineers. It is noted that considerable insight is obtained by the analysis of the procedures (both implicit and explicit) of classical SISO design.
