Abstract: In the context of Networked Control Systems (NCS), communication time delays strongly influence on the Quality of Control (QoC) of process control applications. The goal of this paper is to propose a way to calculate the closed-loop communication time delay and we compensate this time delay using the pole placement design method in order to improve the QoC for CAN-based NCSs. We consider several process control applications implemented on a CAN network. Then we show the interest of the proposed method by comparing the QoC obtained with and without time delay compensation.

Abstract: In this paper we present experiments and projects which gives hands-on experience to the students who start working with microcontrollers initially. As PIC microcontrollers have become popular and are one of the best microcontrollers to start working with in an introductory embedded system laboratory, we have chosen PIC 18F25K20 microcontroller available on the market in a palm size module by name: AMICUS. The exercises described in this paper can be introduced as a one-third semester laboratory course. The AMICUS module is inexpensive and can be used to perform basic and project-based exercises. It is well suited for an under graduate engineering or science course, with electronics, computer science as major. If it is a introductory laboratory course on microcontrollers, it gives an opportunity for the student to use his previous knowledge on basic electronic circuits, digital system design, computer architecture and software development. This paper is not only useful for academics but also useful for amateur electronics hobbyist.
