We consider the implementation of simple process control applications through a CAN network. The goal of this paper is to study modifications on-line of controller parameters according to the global time delay in the control loop. Two methods that we use are the phase margin method and the dominant pole one. We evaluate the performances of the two methods in terms of the time response.
