This unit extends the concepts met within the unit "Linear Systems and Control"
to cover more sophisticated applications. In particular, the following points
are considered :
(i) In all but the most basic control problems, computers out perform any
other type of controller. In the first instance, a computer control
loop may be designed by means of a simple extension of the classical
techniques for continuous systems.
(ii) State space descriptions are generally more efficient than transfer
function algebra in the description of complex systems.
(iii)Many real systems will display non linear characteristics to a degree
which is not accurately described by small signal linear models.
