SYNOPSIS:

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.


OBJECTIVES:

On mastering this unit, the student should be able to exhibit
competence in the :

  1. design of a SISO computer controlled loop;
  2. design of control systems using state space methods;
  3. design and control systems which include non linearities.

OTHER REQUIREMENTS:

1    In  order  to  complete  this unit successfully  a  student  must
     normally   obtain  50%  of  the  marks  in  both  the  individual
     assessments and overall.
2    If  students submit assignments after the due date without  prior
     consultation then a penalty of up to 10% of the assignment  total
     marks will apply for each working day late.
