“…The use of actuators has been tested as early as the 1990s by Honeywell (Hegg, 1995) and is part of the active sidesticks in use today in Gulfstream aircraft from BAE Systems. A design of these actuators has been published in the recent past (Fergani et al, 2016). Different solution is based on hydraulics.…”

The use of passive sidesticks in large transport aircraft equipped with Fly-By-Wire (FBW) has shown several problems related to the lack of force feedback. In the context of the current trend to find ways of introducing FBW systems also in small general aviation and future Urban Air Mobility vehicles, it will be necessary to address, how to control these machines and whether the adoption of passive controls from transport aircraft will be acceptable. This paper summarizes the benefits and challenges associated with the potential application of active sidestick in future small FBW aircraft.

“…Most of the operating forces are measured by using torque sensors. The papers Cavallo et al (2004), Rinaldi and Beckham (1983), Hutton et al (1994), and Fergani et al (2016) installed a pull-up/pressure sensor at the end of the rod to read the applied force at each moment. However, torque sensor occupies large space in both mechanical installation and wiring, which affects the normal operation of the pilots.…”

Dynamic parameters identification of a haptic interface for a helicopter flight simulator

Abstract. The haptic interface force feedback is one of the key factors for a reliable flight simulation. This paper addresses the design and control implementation of a simple joystick-like haptic interface to be used for a helicopter flight simulator. The expression of the haptic interface force is obtained by dynamic analysis of the haptic interface operation. This paper proposes a new strategy aiming at avoiding the use of an expansive and complex force/torque sensor. Accordingly, specific dynamic model is implemented by including Stribeck friction to describe the friction moment. Experimental data are processed as based on a genetic algorithm for identifying the dynamic parameters in the Stribeck friction model. This allows to obtain the friction moment parameters of the haptic interface, as well as the torque distribution due to gravity and the rotational inertia parameters of the haptic interface for the calculation of the haptic interface force. Experimental tests are carried out and results are used to validate the proposed dynamic model and dynamic parameter identification method and demonstrate the effectiveness of the proposed force feedback while using a cheap photoelectric sensor instead of an expansive force/torque sensor.

Mixed Sensitivity Servo Control of Active Control Systems

et al. 2022

The aircraft control system of the future will be a combination of fly-by-wire technology and Active Control System (ACS) which, based on the artificial feel system, provides a control strategy for both position and force. The ACS has uncertainties, such as the mass of the simulated stick, system inertia, system damping and friction. In this paper, aiming at the servo control method of ACS, a mathematical model of ACS was setup. Then, to eliminate the perturbation of the external environment, such as noise and disturbance torque, a robust control method based on H∞ was proposed. Finally, to verify the simulation results, the mathematical model was verified via experimental studies.
