ABSTRACT
This chapter discusses the measured network induced delays using end-to-end and one-end approaches. Both end-to-end and one-end delay measurement results are covered as each has its own importance. In particular, end-to-end delay measurement can be used to introduce a delay compensation mechanism before a message is sent to the destination while one-end delay can be used for overall network and controller optimization. The chapter presents the experiment results on wired link contention. It also discusses control performance assessment for handling wired contention using the exponentially weighted moving average filter. Auto-regressive model with exogenous inputs (ARX) and Kalman filter have been applied for providing reliable signal estimation solutions. Overall the ARX-based Kalman filter requires more processing time as compared with the original ARX model. It is observed that the third-order models require less processing time than the corresponding second-order models. The chapter analyzes the assessment results using the developed real-time simulator Wireless highway addressable remote transducer Hardware-in-the-loop Simulator.
