Methods for Safe Control Systems Design and Implementation

Methods for Safe Control Systems Design and Implementation

This paper is the introductory one of the Safe control systems session. A classification of methods contributing to control systems safety is proposed in order to place the five other papers of this session and to show that they are complementary. This classification is based on a life-cycle criterion. Focusing then on discrete event systems safety, we point out the relationships between state ...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

ORCCAD, a framework for safe robot control design and implementation

Robotic systems are typical examples of hybrid systems where continuous time aspects, related to control laws, must be carefully merged with discrete-time aspects related to control switches and exception handling. These two aspects interact in real-time to ensure an efficient nominal behaviour of the system together with safe and graceful degradation otherwise. In a mixed synchronous/asynchron...

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
