Sammanfattning

The implementation of industrial control applications typically

introduces complexities like sampling jitter and control jitter,

which have usually not been considered at the design stage.

Consequently, the system behaves in a non-periodic manner and the

real performance is degraded with regard to the expected response.

This paper proposes a hybrid task model to reduce the impact of the

scheduling on control performance. For a large batch of typical

plants, we analyze how sensitive a control system is to jitter when

the sampling rate is slow or fast compared to the bandwidth of the

system.
