Abstract :
Dual parameterisation has recently been presented for the class of all stabilising controllers for linear minimum phase rational plants. it is shown that the result can be extended to the parameterisation of all stabilising controllers for linear nonminimum phase rational plants. The parameterisation for nominal plants is a special case of the new parameterisation. Numerical examples are provided to illustrate the new parameterisation.
