“…The skyhook control can reduce the resonant peak of the sprung mass quite significantly and thus achieves a good ride quality by adjusting the skyhook damping coefficient when vehicle body velocity and other conditions are changing. By deriving this idea to reduce the sliding chattering phenomenon, a soft switching control law is introduced [39][40][41][42][43] for the major sliding surface switching activity in Eq. (19), as shown in Fig.…”

A polynomial function supervising fuzzy sliding mode control (PSFαSMC), which embedded with skyhook surface method, is proposed for the ride comfort of a vehicle semi-active suspension. The multi-objective microgenetic algorithm (MOμGA) has been utilized to determine the PSFαSMC controller’s parameter alignment in a training process with three ride comfort objectives for the vehicle semi-active suspension, which is called the “offline” step. Then, the optimized parameters are applied to the real-time control process by the polynomial function supervising controller, which is named “online” step. A two-degree-of-freedom dynamic model of the vehicle semi-active suspension systems with the stability analysis is given for passenger’s ride comfort enhancement studies, and a simulation with the given initial conditions has been devised in MATLAB. The numerical results have shown that this hybrid control method is able to provide real-time enhanced level of reliable ride comfort performance for the semi-active suspension system.

Based on the space tether, the concept of a motorized momentum exchange tether (MMET) using the momentum exchange principle has been proposed for many years. In this paper, a new symmetric configuration of MMET, referred to as HEX-MMET, is proposed. HEX-MMET has some unique advantages, such as higher payload transfer efficiency and shorter orbit reboost period compared to the MMET. In order to study the dynamic characteristic of HEX-MMET, using traditional Lagrange methods, a two-dimensional (2D) dynamic model of HEX-MMET is presented. Then, the numerical solutions based on MATLAB were implemented. The simulation results show that external torque has little evident influence on the orbital parameters, such as the radius of HEX-MMET's center-of-mass (COM) and the true anomaly; however, there is an apparent effect on the attitude parameters, such as the angle between the line of two payloads and the line of local gravity gradient. Furthermore, the gravity gradient torque also effects the attitude of HEX-MMET periodically.

“…For improving the payload transference efficiency, a new kind of applications of the space tether, denoted as motorized momentum exchange tether (MMET), was proposed and has been a hot research topic over the last two decades [8] and further investigated by Robert and Ziegler [9,10]. Additionally, by considering the effect of the tether's axial and torsional oscillation, Chen and Cartmell studied the dynamics of the MMET with axial and torsional oscillation using Lagrange methods and controlled the in-plane angle of the MMET by hybrid sliding mode control strategies [11,12]. In 2013, Murray studied the moontracking orbit for the payload transfer periodically [13,14].…”

This paper presents the error dynamic model of motorized momentum exchange tether (MMET) based on the momentum exchange principle of space tether. The error dynamics are caused by the structural bias of the differences in tethers’ length and the difference in payloads’ mass. After that, the coupling analysis between orbit and attitude is presented. It is shown that, with increasing the differences in tethers’ length and payloads’ mass, the COM deviation of the MMET increases linearly. The numerical simulations of the MMET by considering the structural asymmetries are presented; the results show that the asymmetries have tiny influences on the orbit of the chief satellite by decreasing the apogee, which will change the instantaneous velocity at the apogee and affect the payload injection precision. What is more, the structural asymmetries have effects on the attitude elements (including the pitch angle and yaw angle); however, the effects could be weakened by the external torque. The structural asymmetries and gravity gradient torque have composite effects on the angular velocity of the propulsion tether.
