✦ Synopsis

Methods are presented for designing noninteracting controllers for linear multivariable sampled data systems. The two particular cases considered are as follows: (1) The feedback signal is sampled, but continuous controllers are used. (2) Digital controllers are utilized. The methods are based upon transform analysis of sampled data systems. The design procedures facilitate the selection of physically realizable controllers and allow suitable overall system response.

For the first case, dynamic decoupling is assured not only at the sampling instants but at all times. For the second case, dynamic decoupling is assured only at the sampling instants. It is shown, however, that this is a general result when using digital decouplers and is not particular to the proposed method.
