The on-going development of a full authority digital engine control (FADEC) system for the US Navy’s Intercooled Recuperated (ICR) gas turbine requires a high level of system coordination to achieve the primary benefits of reduced specific fuel consumption and improved specific output power relative to a simple cycle engine. This paper describes the system requirements analysis and the implementation of control algorithms leading to the preliminary ICR control system design. The ICR control system is required to coordinate the actions of over 30 actuators using data taken from over 150 sensors. Primary control of the engine output power is provided by regulation of the fuel metering valve. Thermal management of the intercooler, recuperator, and variable area power turbine nozzle results in maximum cycle efficiency within safe operating limits. The new electronic engine controller (EEC) is based on a new open architecture Futurebus + backplane and is fully redundant in all operationally critical control functions. The EEC also features an operating panel and video display for local operation and maintenance of the control system. The graphic display and function keys provide access to control functions as well as assisting maintenance activities with built-in test diagnostics to trouble shoot failed circuitry.

The on-going development of a full authority digital engine control (FADEC) system for the US Navy’s Intercooled Recuperated (ICR) gas turbine requires a high level of system coordination to achieve the primary benefits of reduced specific fuel consumption and improved specific output power relative to a simple cycle engine. This paper describes the system evolution and the hardware and associated control algorithms implemented in the Advanced Development prototype ICR control system design. The ICR control system is required to coordinate the actions of 58 actuator channels using data taken from 141 sensors. Primary control of the engine output power is provided by regulation of the fuel metering valve. Thermal management of the intercooler, recuperator, and variable area power turbine nozzle results in maximum cycle efficiency within safe operating limits.

NOVA Corporation of Alberta has developed a programmable logic controller based gas turbine fuel control system for natural gas compressor set applications. The system carries out all necessary fuel control functions and was integrated into the existing programmable logic controller used for sequencing and shutdown. The system has been successfully implemented on several different aero derivative gas turbines to date. This paper discusses the development of the system, its performance and advantages over standalone hardware-based fuel control systems typically used in the application.

The Way

This paper describes the way in which Systems Engineering has been used to map out and address the technical, operational and regulatory considerations necessary for autonomous platform management of Unmanned Surface Vehicles. Building on an approach originally developed for Unmanned Aerial Vehicles, Model-Based Systems Engineering has been used to derive the context and requirements for this high-level ship control system to ensure that it is properly structured, adaptable and re-useable. Mapping out use cases of the platform systems of a large, complex unmanned ship has allowed the functional requirements to be derived rigorously and therefore informs the selection of the most efficient architecture and interfaces ahead of software creation. This practical application of Systems Engineering has paved the way to the creation of robust, open-architecture control of platform systems which enables vessel autonomy in the Naval domain.

This paper describes a systematic, consistent approach to control design developed over years of theoretical design and field testing. The Gas Turbine Generator Set control (with some Hover-craft Lift control variations) is discussed both as an example of the design method and as a project on its own merit. This control ideology is not dependent on implementing hardware, high level languages. It is an organic method based on an example of “human” organization, the corporation. The Gas Turbine control is an interactive corporate team; member personalities and duties are the logic. The rationalized I-T-E (if-then-else) method of defining and programming the control (corporate) personalities is used by the turbine and controls engineers to efficiently produce the final turbine and machinery control algorithms. A simple integrated software/hardware scheme facilitates recording and executing these algorithms. Last but not least, reliable control performance must be achieved through an inherently fail-safe “systems” approach.

Thermocouples have been installed in gas turbine exhaust gas paths for decades for control functions. Since the late 1970s, such thermocouples have also been used for combustion monitoring. The purposes for these thermocouples and the use of the information they provide are sometimes misunderstood. When properly situated and incorporated into a control system, these devices provide data that can ensure a properly operating combustion system, prevent catastrophic hot parts failures, extend component life, and increase availability. Although the use of blade path thermocouples for combustion monitoring has generally been associated with later model gas turbines using cannular combustors, their advantages can also be realized by the modification of older cannular gas turbines as well as turbines with annular or silo combustors. This paper reviews the concept and summarizes the benefits of blade path monitoring and the use of the temperature information obtained. A recommendation is made for the retrofit of older engines and the enhanced instrumentation of some later frames.

Greatly improved availability is the primary design goal of the SPEEDTRONTC Mark IV Gas Turbine control. It achieves this goal by distributing control functions among four microcomputers: three are identical control sections, and the fourth handles communications. Powerful on-line diagnostics indicate which section is faulty, down to the replaceable element. Panel repair is effected with the gas turbine running. Mean time to repair is predicted to be three to four hours. The prediction is that the SPEEDTRONIC Mark IV control will not cause a plant shut down more often than once in ten years. In addition, the system has capacity for redundant sensor inputs, which significantly reduces forced outages caused by faulty sensors. Information on how these results were accomplished is presented in the paper, along with a description of the initial experiences running gas turbines with the new system.

Cloud Control System

AbstractThe electrification of vehicle helps to improve its operation efficiency and safety. Due to fast development of network, sensors, as well as computing technology, it becomes realizable to have vehicles driving autonomously. To achieve autonomous driving, several steps, including environment perception, path-planning, and dynamic control, need to be done. However, vehicles equipped with on-board sensors still have limitations in acquiring necessary environmental data for optimal driving decisions. Intelligent and connected vehicles (ICV) cloud control system (CCS) has been introduced as a new concept as it is a potentially synthetic solution for high level automated driving to improve safety and optimize traffic flow in intelligent transportation. This paper systematically investigated the concept of cloud control system from cloud related applications on ICVs, and cloud control system architecture design, as well as its core technologies development. Based on the analysis, the challenges and suggestions on cloud control system development have been addressed.
