A new pitch angle adaptive control design

Abstract

This paper presents a new pitch angle adaptive control design based on the pitch rate following of a desired trajectory that ensures closed loop satisfactory performance. The pitch rate is under adaptive predictive (AP) control, as previously seen in the literature, but its desired trajectory is produced by a guidance block within a global guidance system structure that ensures automatic pitch angle closed loop performance. Additionally, the guidance block presented in this paper allows satisfactory operation of the automatic pilot in a range of high control frequencies suitable for this kind of application, overcoming stability problems that may arise within these high frequencies by direct application of a pitch angle AP controller. Experimental results obtained by flying a simulated aircraft illustrate comparatively the guidance system performance, and show the robustness of the new design with aerodynamic disturbances.

Detección de anormalidades en el control de estabilidad de una aeronave

“…Se analiza la estabilidad del sistema en lazo cerrado y se demuestra la viabilidad y la validez del controlador en una simulación la aeronave. En [5] se propone un controlador adaptativo predictivo para la regulación de la velocidad de cambio del picth siguiendo una trayectoria predeterminada para asegurar un desempeño satisfactorio del sistema en lazo cerrado. En [6] se presenta una metodología de diseño de control inteligente para el diseño un controlador difuso para aeronaves comerciales que operan en condiciones de vuelo anormales.…”
