Integrated Design and Control of a Flying Wing Using Nonsmooth Optimization Techniques

Multicontrol Surface Optimization for Blended Wing–Body Under Handling Quality Constraints

“…A single bandwidth and damping of, respectively, ω 0 8.8 rad ⋅ s −1 (1.4 Hz) and ξ 0.8 was used. Previous studies considered allocating different bandwidths for all control surfaces [14,39]; however, this is outside the scope of the present paper. A 100 ms delay accounting for sensors, computers, and data processing is included in the control law synthesis and simulation.…”

“…Consequently, several approaches seek to solve these combined problems in a single step. "Plant-controller optimization" has been studied in a variety of fields, such as chemistry [19,20], autonomous underwater vehicles [21], and astronautics [14,22,23].…”

Optimal codesign of controller and linear plants with input saturation: The sensitivity Lyapunov approach

“…For some 0 < c 1 < c 2 < 1. Equation 14 ensures an improvement in the search when d is a descent direction. Note that Equation 14 will be satisfied for any small α because of Lemma 1, in which case the improvement may be limited.…”

“…Equation 14 ensures an improvement in the search when d is a descent direction. Note that Equation 14 will be satisfied for any small α because of Lemma 1, in which case the improvement may be limited. Therefore, the curvature condition (15) is added to ensure that the chosen step length is not too conservative.…”

Handling Qualities Optimization in Aircraft Conceptual Design

“…One of the most notable examples are flying wings. By careful positioning of the center of gravity, it is possible to achieve static stability for these configurations as well, even though in most of the cases they require the presence of a stability augmentation system to ensure adequate flight characteristics [33][34][35].…”
