“…Hydraulic driving and controlling technologies are generally adopted in different walks of life, such as engineering construction, metallurgy, mining, national defense and materials. The oil acts as a crucial medium for the energy transmission and information coupling in the hydraulic transmission system, where its compressibility affects the stiffness [1]- [3], control accuracy [4], [5], dynamic and the nonlinear performance [6]- [9] of the system. Moreover, in the fields such as fault diagnosis [10], [11], condition monitoring [12], and reliability research, without paying attention to the nonstationary compressibility of the oil would cause misjudgment of the system running state.…”

“…However, due to the special structure of two vehicle parts connected by two hydraulic struts and one articulation joint without locking mechanism [3][4][5] , the front and rear vehicle parts can rotate relatively, which easily make DAHVs produce oscillatory yaw motion during moving process, especially with the external disturbance. Moreover, the hydraulic struts is inevitably entrained with gas and produce leaks, which can decrease the vehicle torsional stiffness and increase the oscillatory yaw motion or even lead to instability for DAHVs [6,7] .…”

“…Therefore, autonomous UAVs are urgently needed. Because of the specialty of steering, the lateral precise control of UAV is an important issue [4,5], which is usually based on the dynamic model and steering characteristics of the UAV. The steering characteristics reflect the control performance, and are the main means to evaluate the handling stability and path tracking of the vehicle [6][7][8].…”

“…Nayl [17,18] et al studied the effect of kinematic parameters on a motion planning system, and the kinematic model was used during the process of modeling and control. Gao [4] et al established a 12 DOF dynamic model of UAV and uncovered the instability area considering the influence of bulk modulus of hydraulic oil. Based on the instability results, an Ackman-based hierarchical controller was designed to improve the stability of UAVs.…”
