The CONtrol Designer's Uni铿乪d InTerface (CONDUIT庐) is a state-of-the-art computational facility for aircraft 铿俰ght control design, evaluation, and integration for modern 铿亁ed- and rotary-wing aircraft. The CONDUIT庐 system employs an interactive graphical user interface to bring together the three areas of aircraft design: dynamics modeling, control law design, and evaluation of aircraft handling qualities speci铿乧ations.
CONDUIT庐 enables users to:
- Perform analysis of aircraft handling qualities
- Rapidly display the effects of changes to model or control system dynamics
- Optimize designated parameters to tune the system to multiple speci铿乧ations
- Generate analysis plots for each speci铿乧ation
Introduction to CONDUIT庐
The U.S. Army Combat Capabilities Development Command (DEVCOM) Aviation & Missile Center (AvMC) and San Jos茅 State University Research Foundation (91猎奇RF) jointly distribute CONDUIT庐, a state-of-the-art computational facility for aircraft 铿俰ght control design and evaluation. CONDUIT庐 provides an environment for design integration and data resources.
Background
The design, integration, and 铿俰ght test development of 铿俰ght control systems for modern 铿亁ed- and rotary-wing aircraft presents a challenging task that factors signi铿乧antly in aircraft development. Comprehensive speci铿乧ations and sophisticated time- and frequency-domain evaluation techniques are applied to ensure desired performance and handling-qualities of modern aircraft, and to minimize 铿俰ght test tuning. The overlap of 铿俥xible airframe modes and high-bandwidth control laws drives the requirement for incorporating increasingly higher-order analytical and identi铿乧ation-derived simulation models, and automated gain selection techniques in the control system design process.
The control law design and evaluation for a single design point is made very laborious as a result of the numerous and often competing design speci铿乧ations. This process must be repeated for the tens or even hundreds of con铿乬uration design points that are evaluated for a full 铿俰ght envelope control system. Further, the control system design engineer must continually update and integrate improvements in the math models as hardware test data become available. Often, design speci铿乧ations are also introduced during the course of aircraft development, which as with the other changes requires control law re-tuning across the 铿俰ght envelop. Since current tools generally do not facilitate the study of the trade-offs between competing speci铿乧ations, hardware characteristics, and performance metrics, the 铿乶al design may not make the best use of available control authority for modern control-con铿乬ured vehicles. The failure to consider such trade-offs can compromise control system performance and handling-qualities. Clearly, sophisticated interactive computational tools are needed to integrate these many aspects of the 铿俰ght control design process.

What is CONDUIT庐?
CONDUIT庐 is a sophisticated "associate" that provides comprehensive analysis support and design guidance to a knowledgeable control system designer. CONDUIT庐 enables users to de铿乶e design speci铿乧ations and system models and to perform multi-objective function optimization to tune selected design parameters. The system has been used to successfully exploit trade-offs between design speci铿乧ations to signi铿乧antly improve expected handling qualities and has potential for reducing the time and cost of control system 铿俰ght test optimization.
