Position and Rate Saturations Authors: Francesco Amato, Raffaele Iervolino, Madhukar Pandit, Stefano Scala, Leopoldo Verde, Volume: 1, Page 3564 Paper number 2050 Abstract: In this paper we deal with the analysis of Category II (nonlinear) Pilot in-the-Loop Oscillations (PIO). PIO phenomena are originated by a misadaptation between the pilot and the aircraft that causes sustained or uncontrollable oscillations, which especially occur during some tasks where tight closed loop control of the aircraft is required from the pilot. Category II PIO are those oscillations that can strictly be correlated with the activation of rate and position limiter elements in the closed loop pilot-vehicle system. This kind of nonlinearity is unavoidably present in every aircraft, because of physical constraints of elements such as stick/column deflections, actuators position and rate limiters, limiters in the controller software and so on. In this paper we propose an approach, based on the describing function technique, to evaluate the nonlinear effects of the simultaneous presence of position and rate saturations in the control loop. The X-15 landing flare PIO is used as test case to demonstrate the effectiveness of the method. CD002050.PDF (From Author) TOP A Backstepping Design for Flight Path Angle Control Authors: Ola Härkegaard, S. Torkel Glad, Volume: 1, Page 3570 Paper number 1847 Abstract: A nonlinear approach to flight path angle control is presented. Using backstepping, a globally stabilizing control law is derived. Although the nonlinear nature of the lift force is considered, the pitching moment to be produced is only linear in the measured states. Thus, the resulting control law is much simpler than if feedback linearization had been used. The free parameters that spring from the backstepping design are used to achieve a desired linear behavior around the operating point. CD001847.PDF (From Author) TOP Attitude Control of the Airborne Telescope SOFIA: mu-Synthesis for a Large Scaled Flexible Structure Authors: Ulrich Schönhoff, Ascan Klein, Rainer Nordmann, Volume: 1, Page 3576 Paper number 1791 Abstract: The airborne observatory SOFIA is in development with the intent to provide astronomers access to infrared wavelength unavailable from the ground. The operation of the telescope under the harsh environmental conditions in the aircraft makes the quality image stability a crucial issue. To evaluate the limits of performance that can be reached by the attitude control, a m-synthesis optimization of the control loop is investigated during the conceptual design. A finite element model offers the most precise description of the structural dynamics of the telescope structure in this design phase and is chosen as basis for the controller design. The paper focuses on the practical aspects of robust controller design such as plant and controller reduction, weighting function selection and uncertainty modelling for flexible structures. CD001791.PDF (From Author) TOP Aggressive Maneuvering Of A Thrust Vectored Flying Wing: A Receding Horizon Approach Authors: John Hauser, Ali Jadbabaie, Volume: 1, Page 3582 Paper number 1946 Abstract: This paper deals with the control of a thrust vectored flying wing known as the ducted fan, developed at California Institute of Technology. The experiment was developed to serve as a testbed for nonlinear control design. In an earlier paper, the authors reported simulation results based on a simplified (no aerodynamics involved) planar model of the ducted fan around hover position. In this paper we report on the modeling and simulation of the ducted fan in forward flight, where aerodynamic forces and moments can no longer be ignored. A receding horizon scheme is developed to generate trajectories for the forward flight model. Using a more simplified version of the model, some aggressive trajectories are generated. These trajectories are then used as a reference in the receding horizon scheme, and morphed into the trajectories of the full model. Simulation results depict the capabilities of the ducted fan as well as this methodology in performing aggressive maneuvers. CD001946.PDF (From Author) TOP Global Configuration Stabilization For The VTOL Aircraft With Strong Input Coupling Authors: Reza Olfati-Saber, Volume: 1, Page 3588 Paper number 1099 Abstract: Trajectory tracking and configuration stabilization for the VTOL aircraft (vertical take off and landing) in the literature has been only considered for the case of slight or zero input coupling. In this paper, our main contribution is to address global configuration stabilization for the VTOL aircraft with a strong input coupling using a smooth static state feedback. CD001099.PDF (From Author) TOP Robust Output Regulation for Autonomous Vertical Landing Authors: Lorenzo Marconi, Alberto Isidori, Volume: 1, Page 3590 Paper number 101 Abstract: In this paper we consider the design of an autopilot for the autonomous landing of a VTOL air vehicle on a ship whose deck oscillates in the vertical direction due to high sea states. The deck motion is modeled as the superposition of a fixed number of sinusoidal functions of time of unknown amplitude and phase. We design an internal-model based error-feedback dynamic regulator that is robust with respect to uncertainties on the mechanical parameters that characterize the model and secures global convergence. CD000101.PDF (From Author) TOP Design of a STT Missile Autopilot Using Functional Inversion and LMI Approach Authors: Seong-Ho Song, Sang Yong Lee, Jeom Keun Kim, Gyu Moon, Seop Hyeong Park, Sun Yong Kim, Volume: 1, Page 3596 Paper number 1019 Abstract: In this paper, we present a novel systematic approach for the autopilot design of STT missiles. First, the nonlinear model of a STT missile is partially linearized via functional inversion techniques and then, the additional set-point tracking controller can be designed by the well-known LMI approach. The stabilization conditions are given in terms of LMI's. CD001019.PDF (From Author) TOP
