Jitter Evaluation of Real-Time Control Systems

• 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.
