Real-time control of non-uniformly sampled systems

Abstract Industrial applications of digital control require a synergy between well-designed control algorithms and carefully implemented control systems. The design of digital controllers should not be constrained to the simplest case of a single rate with sychronous sampling strategies, and the digital implementation should take account of the actual real-time operating environment. In this paper, control design techniques under non-uniform sampling schemes are reviewed, and computer improvements to cancel or reduce the effect of delays and process interactions are presented.
