Control Performance Analysis of a CAN – Based Networked Control System: Active Suspension Study Case

In this paper a performance analysis of a Networked Control System (NCS) based in Controller Area Network (CAN) is presented. The analysis is done considering three variables of CAN: baud rate, priority of message and network load. These parameters directly affect the network delay and in consequence the feedback control performance. An active suspension model is considered and extensive experimental results have been performed to demonstrate the influence of these parameters in the quality of control performance. An experimental system which includes a pedagogic scale model with real car components was exploited.
