Abstract:
This Dissertation deals with how to support the Real-Time Applications in Control System. First of all reviewing the characteristics of real-time applications. Observing that, contrary to the popular view that Real-Time Applications necessarily require a fixed delay bound. Some real-time applications are more flexible and can be adapted to current control conditions. Real-time Control Services support two distinct kinds of real-time service: guaranteed service, which is the traditional form of real-time service, discussed in most of the literature and involves pre-computed worst-case delay bounds. The second is predicted service which uses the measured performance of the control mechanism this one can support both of these real-time services as well as. Also discusses two other aspects of real-time architecture: the interface and the admission control criterion.
In this project, a simple problem was studied with consideration of how a real-time system can be specified and implemented to meet the requirements. The practical work describes the implementation of a real-time controller for a d.c motor which has been developed in a PC using Simulink and Real-Time workshop. This methodology is totally based on the use of open source software, which is easily available. The projects introduced into three main parts are outlined: real-time system concept and related theoretical approach, control system design and, finally, real-time implementation.
