LMI–based robust controller design approach in aircraft multidisciplinary design optimization problem

Aircraft Design Optimization with Multidisciplinary Performance Criteria

By minimizing a cost function consisting of both conventional performance criteria and a measure of aircraft handling qualities, a design with maximum performance for a specified level of handling can be achieved. Handling qualities are measured using a quadratic cost function similar to that used in the design of optimal feedback control systems. This function is proportional to the difference...

A Robust Design Approach for Achieving Flexibility in Multidisciplinary Design

Aircraft Design Markup Language for Multidisciplinary Aircraft Design and Analysis

The process of conceptual aircraft design has advanced tremendously in the past few decades due to rapidly developing computer technology. Today’s modern aerospace systems exhibit strong, interdisciplinary coupling and require a multidisciplinary, collaborative approach. Efficient transfer, sharing, and manipulation of aircraft design and analysis data in such a collaborative environment demand...

Evaluation of Multidisciplinary Optimization Approaches for Aircraft Conceptual Design

This paper presents the evaluation of different MDO architectures using an extended set of metrics, which take into consideration optimization and formulation structure characteristics. Demonstrative comparisons are made for analytic and supersonic business jet conceptual design examples. Results show the promising features of the proposed evaluation metrics to define a standardized guideline w...

Reliability-Based Multidisciplinary Optimization for Aircraft Wing Design

Aircraft wing design typically involves multiple disciplines such as aerodynamics and structure. Multidisciplinary design optimization (MDO) has been recently used to deal with the multidisciplinary efforts in wing design. When reliability is considered, MDO for the wing design becomes much more computationally intensive. To improve the efficiency, the strategy of using Sequential Optimization ...
