This paper proposes a comparative analysis to understand the effects of Networks and Scheduling techniques on Network Control System. The main contribution of this work is to see effects on stability of the control system by using Ethernet and Controller Area Network. And then further analyze it with creating variation via scheduling methods. This is achieved by using an example of network-based servo control system from the Matlab TrueTime toolbox 2.0. This model is designed in Simulink and each system is initialized using m.file in Matlab. The model used in this work consists of three network nodes; an interference generator, a plant (Servo motor with an actuator and a sensor) and a controller, all connected by a network. Four different case studies were developed and discussed such as Ethernet, Controller Area Network, Scheduling, Scheduling on control node. It helped to establish the superiority of the Controller Area Network, effects on data loss and use of right scheduled algorithm for stable real time control system. This comparative study will help a control engineer to decide a precise parameter, while designing a Real time network control system.
