Design of sampled-data multivariable control systems using the inverse Nyquist array

Rosenbrock's inverse Nyqviist array design method for continuous multivariable systems is extended to the design of multivariable sampled-data systems. The effects of sampling and incorporating zero-order holds in the system are shown to play important roles in the design procedure. A design example is presented to illustrate the approach developed, and the results obtained are compared with previous work.
