This study presents roll angle, lateral, and longitudinal acceleration autopilots for a highly agile air defense missile with both aerodynamic tail control and thrust vector control (TVC) parts. Nonlinear Dynamic Inversion (NDI) is studied to handle bank-to-turn and agile maneuvers due to the cross-coupling effects. Output redefinition is implemented using the center of percussion idea for the nonminimum phase of the tail-controlled missiles. Another arduous feature of the system is that the dual control of the system generates a need to allocate the control between aerodynamic and thrust control. Driving aerodynamic fins and jet vanes with the same actuator is found preferable for some systems that creates a mechanically coupled or, in other words, integrated design. Further, this paper shows the effect of allocating control with or without this mechanical coupling.

Control and Robustness Analysis for a High-alpha Maneuverable Thrust-Vectoring Fighter Aircraft Atesoglu, Oezguer; Özgören, Mustafa Kemal (2009-09-01) This study focuses on designing a nonlinear controller for high-alpha maneuvers of a fighter aircraft with a thrust-vectoring control ability and checking the robustness of the designed controller using the structured singular-value mu-based robustness analysis. The controller is designed using the nonlinear dynamic inversion method. It is designed, to engage either the aerodynamic control surfaces or the thrust-vectoring control paddles of the engines, depending on the flight conditions. The necessary math...
Single channel digital controller design for a high spinning rate rolling airframe missile Suicmez, E. C.; Kutay, Ali Türker (2022-04-01) Spinning/Rolling Airframe Missiles (RAM) mostly use an analog (ON-OFF type) control approach that deflects control surfaces (fins) at minimum and maximum positions continuously, and control is achieved by applying phase shift between the minimum and maximum deflections during a complete roll cycle. Therefore, the control signal shape changes continuously during the roll cycle. In this study, a novel single channel digital controller is designed and tested for a high spinning rate (10-20 Hz) RAM. The digital...
Control System Design of a Vertical Take-off and Landing Fixed-Wing UAV Cakici, Ferit; Leblebicioğlu, Mehmet Kemal (2016-05-20) In this study, design and implementation of control system of a vertical take-off and landing (VTOL) unmanned aerial vechicle (UAV) with level flight capability is considered. The platform structure includes both multirotor and fixed-wing (FW) conventional aircraft control surfaces: therefore named as VTOL-FW. The proposed method includes implementation of multirotor and airplane controllers and design of an algorithm to switch between them in achieving transitions between VTOL and FW flight modes. Thus, VT...
Nonlinear Dynamic Inversion Autopilot Design for an Air Defense System with Aerodynamic and Thrust Vector Control Bıyıklı, Rabiya; Yavrucuk, İlkay; Tekin, Raziye; Department of Aerospace Engineering (2022-2) The study proposes complete attitude and acceleration autopilots in all three channels of a highly agile air defense missile by utilizing a subcategory of nonlinear feedback linearization methods Nonlinear Dynamic Inversion (NDI). The autopilot design includes cross-coupling effects enabling bank-to-turn (BTT) maneuvers and a rarely touched topic of control in the boost phase with hybrid control which consists of both aerodynamic fin control and thrust vector control. This piece of work suggests solut...
Aeroelastic Modelling and Testing of a Thin Laminated Composite Missile Fin/Wing Aslan, Göktuğ; Kırımlıoğlu, Serdar; Kurtuluş, Dilek Funda (null; 2017-06-09) Missile fins or wings exposed to different coupled aerodynamic loads during the mission or flight at subsonic and supersonic velocity profile. Aerodynamic loads varying with the angle of attack and the velocity profile may cause some structural fatigue and failure problems. In order to achieve such problems, high strength materials such as composites are required. In this work, a laminated composite missile fin was investigated in terms of the strength varying with the aerodynamic profile. The fiber orienta...
