Digital control of continuous time processes is usually designed on the basis of a constant sampling rate. In some digital flight control designs it is difficult to preserve this simplification, so it is necessary to design irregular sampling patterns. The problem could be much more complex if there were various subprocesses with different performances either in time or frequency domains. A new way of design these kinds of controllers are presented. The approach deals with the irregular sampling in the digital flight control. The method presents accurate and optimal results.
