Abstract

For computer-controlled systems (CCSs), actual sampling intervals inevitably deviate from its nominal sampling period, called sampling interval jitter (SIJ), which may degrade control performance and even unstabilize control systems. So it should be accounted for at design time. The model of CCSs with SIJ is presented and its effects on CCSs is illustrated by simulation. The model developed costs less computation resources and can be extended to deal with controller design.
