Predictive Gust Load Alleviation Control Using Leading Edge Stagnation Point Sensor

Completed Technology Project

Project Description

Predictive Gust Load Alleviation Control Using Leading Edge Stagnation Point Sensor
ZONA Technology, Inc. proposes an R&D effort to develop a Gust Load Alleviation (GLA) control system using a novel Leading Edge Stagnation Point (LESP) sensor that has the nearly instantaneous predictive capability. The real-time gust information from the sensor will enhance the performance of the proposed GLA control system. The GLA control method we will adopt is the Generalized Predictive Control (GPC), which consists of identification of the flexible system perturbed by gusts and minimization of the prediction response error by optimal control design. The GPC scheme has a "feedback and feedforward" topology and solves Multi-Input Multi-Output control problems. The measurements of gusts via the LESP sensor, which reduces the inherent delay associated with conventional sensing of the structural responses, can be incorporated into the controller in the feedforward path, hence the GLA performance is improved. ZONA will further assess the effectiveness of the control system on a high fidelity model of a Body Freedom Flutter vehicle, which is a flexible flying wing configuration vehicle designed and flight tested by Lockheed Martin Aeronautics Company.
