Rosetta Common Check-Out and Control System: A Challenge and a Way to Reduce Cost

This work reviews the innovative and progressive methods of determination and analysis of safety objectives using Vilnius A-SMGCS example. The aim of the analysis is to determine how failures in this system could affect flight safety in Vilnius aerodrome. Identified safety objectives will limit the frequency of occurrence of hazards enough for the associated risk to be acceptable, and will ensure that appropriate mitigation means are reflected subsequently as Safety Requirements for the system. Analysis reflects aspects of A-SMGCS Safety objectives, which should be taken into consideration.

And Control

Electro-hydraulic systems (EHS) are widely used in industrial applications due to the high-power density and accuracy. However, EHS are highly nonlinear which makes its modelling and control aspects a complex process. In this paper, we present the modelling and position control for an electro-hydraulic system (EHS). The mathematical modelling is carried out considering the non-linearities like friction, discharge coefficient and load mass present in the system. A back-stepping control scheme is developed for maintaining the accuracy in the position control. The closed-loop stability of the proposed control system is analyzed with Lyapunov’s theory. The performance of the control system under the effect of bounded external uncertainties is validated with simulation study. The study indicates that the proposed controller gives an effective motion control in presence of the system uncertainties.

Automatic Data Acquisition

Abstract Automatic data acquisition and control have become an indispensable part of engineering but many data acquisition and control equipments remain relatively inflexible and cumbersome for most engineering applications. Hence, engineers often need to custom design and build their data acquisition and control system to support their in-house automatic testing and monitoring equipment. This project investigates the design fundamentals and guidelines in setting up a flexible data acquisition and control system. A flexible data acquisition and control system (FDACS) is defined as one which possesses such characteristics as the ease of implementation, the ease of upgrading system’s capability (e.g. data volume and control channels) and the ability for information sharing. An experimental data acquisition system is used as the platform to facilitate the study. It consists of an IBM compatible personal computer, a remote host microprocessor and seven signal processors. Using this implementation, the system is able to provide up to 28 digital I/O lines, 28 analog input lines, 42 digital output lines and an average execution time per instruction of 1 ms.

The Multi-Purpose Model represents a new methodology for developing model based tools for control system design and verification. The Multi-Purpose Model, as described in this paper, simulates a SOFC hybrid system — a challenging and innovative application of dynamic modelling and control. Real-time modelling is a recognised approach to monitor advanced systems and to improve control capabilities. Applications of Real-Time (RT) models are commonly used in the automotive and aerospace fields. Starting from existing TRANSEO components and models, a new approach to fit hybrid system application has been developed. Original C-based models have been translated into embedded Matlab functions for direct use within Matlab-Simulink. The resulting models have then been used to autogenerate c-code with the Real-Time Workshop. The C-code has then been compiled to produce application specific executables.

Drive Pump

In order to provide a solution of active rectification for linear pumps in pump control system, a novel collaborative rectification structure is conceptually designed in this paper. The fundamental subsystem is the direct drive pump cell (DDPC). A DDPC consists of a cylinder and a valve, and the piston rod and the valve spool are integrated together. The DDPC could be driven by a linear oscillating motor directly. The DDPC working process is logically modeled as a state machine. Certain theorems are given and proved to illustrate the composition principles of a pump system with collaborative rectification. The kinematic flow rate of the collaborative rectification pump is studied. According to the comparison to the existing linear pumps, the novel pump has more structure compactness and control flexibility.
