چکیده

This paper analyses the performance of an Attitude and Orbital Control System for the Olympus Satellite. The system was designed using HRT-HOOD and implemented in Ada 83 augmented with some of the facilities of Ada 9X. The program consisted of multiple tasks communicating via protected shared data areas. A worst case execution time analysis tool was used to estimate the execution time of each task, and Deadline Monotonic schedulability analysis was used to predict the system performance, taking into account all kernel overheads. An instrumented version was also produced to gather statistics on the actual run-time performance.

A Non-Preemptive Two-Class M/M/1 System with Prioritized Real-Time Jobs under Earliest-Deadline-First Policy

This paper introduces an analytical method for approximating the performance of a two-class priority M/M/1 system. The system is fully non-preemptive. More specifically, the prioritized class-1 jobs are real-time and served with the non-preemptive earliest-deadline-first (EDF) policy, but despite their priority cannot preempt any non real-time class-2 job. The waiting class-2 jobs can only be s...

Multiobjective Retuning the Power System Stabilizer (PSS) of a Real Power Plant in Iran Grid

The safe operation of power system depends on its stability and security supply in all times. The dynamic instability (small signal instability) is one of phenomena that results in power system instability and has been discussed as a challenge in power system control and operation from a long time ago. Commonly the dynamic instability appears as undamped low frequency electromechanical oscillat...

Comparing supply side and demand side options for electrifying a local area using life cycle analysis of energy technologies and demand side programs

The main aim of this paper is to select the best portfolio of renewable energy technologies (RETs) for electrifying an elected area which is not connected to any other grids. Minimizing total costs of the system is considered as the main factor in finding the best decision. In order to make the optimum plan more applicable, the technique of life cycle analysis is applied. This technique takes i...
