Abstract

A non-uniform additive pseudo-random sampling pattern (mainly proposed in the signal processing communities) can be used for performing an ‘alias-free signal sampling’ process. The carefully designed sampling scheme can mitigate the effects of aliasing and permit significant reductions in the average sampling frequency, leading to more efficient processor utilization. Despite the fact that the sampling scheme potentially yields a number of advantages, has previously received no significant attention in the field of control theory for research. This paper highlights the implementation of this technique in digital control compensators, discussing the importance of selecting a suitable form for implementation and illustrates the potential benefits in terms of alias avoidance
