Architecture And Design

Most modern fighter aircraft are multi-role by design and rely heavily on a number of systems that are computer controlled in real time for achieving the most optimal performance. This paper presents three important real time control systems designed for the Indian Light Combat Aircraft. These are the flight control system, the anti-skid brake control system and the environment control system. Design objectives for these systems along with a description of their various hardware elements, software architecture and design concepts have been presented here. All the systems house extremely critical functions during different phases of flight, and so are designed for high degrees of reliability and extremely low failure probabilities. The concepts adopted for redundancy management, failure identification and failure handling are also presented.

Time Control

The progress of embedded control systems in the last several years has made possible the realization of highly-effective controllers in many domains. It is essential for such systems to provide effective performance at an affordable cost. Furthermore, real-time embedded control systems must have low energy consumption, as well as be reliable and timely. This research investigates primarily the feasibility of implementing an embedded real-time control system, based on a low-cost, commercially off-the-shelf (COTS) microcontroller platform. It explores real-time issues, such as the reliability and timely response, of such a system implementation. This work presents the development and performance evaluation of a novel real-time control architecture, based upon a BeagleBoard microcontroller, and applied into the PWM (pulse width modulation) control of a three-phase induction motor in a suction pump. The approach followed makes minimal use of general-purpose hardware (BeagleBone Black microcontroller board) and open-source software components (including Linux Operating System with PREEMPT_RT real-time support) for building a reliable real-time control system. The applicability of the proposed control system architecture is validated and evaluated in a real case study in manufacturing. The results provide sufficient evidence of the efficiency and reliability of the proposed approach into the development of a real-time control system based upon COTS components.

Abstract The National Institute of Standards and Technology (NIST) has been using the Real-time Control System (RCS) Reference Model Architecture for building control systems based on a hierarchy of cyclically executing control modules. This paper describes the work done to build Java tools that allow developers to lay out their hierarchy according to RCS tenets and view or change the inputs and outputs of each module at run-time.

Tunnel System

This paper presents results from an application of a newly developed simulation tool for pollution based real time control (PBRTC) of urban drainage systems. The Oslo interceptor tunnel is used as a case study. The paper focuses on the reduction of total phosphorus Ptot and ammonia-nitrogen NH4-N overflow loads into the receiving waters by means of optimized operation of the tunnel system. With PBRTC the total reduction of the Ptot load is 48% and of the NH4-N load 51%. Compared to the volume based RTC scenario the reductions are 11% and 15%, respectively. These further reductions could be achieved with a relatively simple extension of the operation strategy.
