Robust Control Design for the Elevation Axis Stabilization of the M256E1 Long Gun
Abstract
A key feature of the Abrams tank is the ability to deliver precision fire during on-the-move vehicle operation. The increased flexibility of a longer gun tube presents a significant additional challenge to stabilization system design. To address the increased difficulties of this problem, an approach to gun stabilization is presented that uses modern robust control techniques to achieve muzzle-pointing accuracy. Such control design methods are model-based, and thus require an accurate mathematical description of the system dynamics. Following a brief description of the model used, the control objectives of performance and robustness are cast in a general framework that precisely quantifies these design goals as optimization objectives. The method of micro-synthesis is then applied, yielding a controller that realizes the objectives. The effectiveness of this control design is illustrated via its implementation in the M256E1 Long Gun demonstration vehicle. Test results of the new controller are compared with a 'classically' tuned controller.
