System security and reliability play an important role in the engine electronic control system airworthiness certification process. System performance validation tests and environmental tests are the most important and effective method to determine and verify the system secrurity and reliability. In this paper,the process and main point for the engine control system certification will be given based on the Performance Validation Tests and Environmental Tests.

Abstract. Modular modeling method was adopted to build model for the engine’s electronic control system , including the engine system model, sensor model, controller model and actuator models. For the engine system, the modeling approach of the average value was used to establish an air supply system model, the fuel supply system model and the engine power take-off model. By the method of mathematical fit, a mathematical model of electronic control engine’s sensors was established. Based on Mat-lab/Simulink, it designed simulation system and proceeded simulation tests for each model of engine control system, then the results show that the model is correct, and it can manifest the changes of relevant parameters during the actual operational process of the engine.

The performance of Diesel engine control system influence the engine combination property directly. The traditional mechanical control system can't meet the requirements of the fuel consumption and emissions. We should turn to the advanced electronic control system. This article introduced the basic frame and control mode of low-speed common rail diesel engine electronic control system, and according to the control object, the whole control system is divided into different modules to detailed analysis.

This paper describes the design and development of a full authority Digital Engine Control and intelligent cockpit Command Box by Dowty and Smiths Industries Controls Limited (DSIC) under a Ministry of Defence and Private Venture demonstrator program. The aims of this program are to: (1) demonstrate the recent and continuing improvements in IC technology and allied computing power; (2) employ control laws more relevant to electronic control, thus absolving the hydromechanical unit from precise fuel metering; (3) improve, by a quantum leap, the methods of monitoring engine/system performance. This control system has undergone successful engine running on a Rolls-Royce GEM, and will shortly be tested, in prototype form, in a Lynx.

Abstract Subglacial lake exploration is of great interest to the science community. RECoverable Autonomous Sonde (RECAS) provides an exploration tool to measure and sample subglacial lake environments while the subglacial lake remains isolated from the glacier surface and atmosphere. This paper presents an electronic control system design of 200 m prototype of RECAS. The proposed electronic control system consists of a surface system, a downhole control system, and a power transfer and communication system. The downhole control system is the core element of RECAS, and is responsible for sonde status monitoring, sonde motion control, subglacial water sampling and in situ analysis. A custom RS485 temperature sensor was developed to cater for the limited size and depth requirements of the system. We adopted a humidity-based measurement to monitor for a housing leak. This condition is because standard leak detection monitoring of water conductivity may be inapplicable to pure ice in Antarctica. A water sampler control board was designed to control the samplers and monitor the on/off state. A high-definition camera system with built-in storage and self-heating ability was designed to perform the video recording in the subglacial lake. The proposed electronic control system is proven effective after a series of tests.
