A systematic differentiator-based adaptive backstepping control methodology is proposed for a class of sandwich-like nonlinear system with unknown state-dependent deadzone nonlinearity and parametric uncertainties. The novelty of our approach is that a high-order sliding mode differentiator is utilized to estimate the nonstrict feedback coupling te...

With the rapid development of computer technology, automatic control technology and communication technology, research on unmanned aerial vehicles (UAVs) has attracted extensive attention from all over the world during the last decades. Particularly due to the demand of various civil applications, the conceptual design of UAV and autonomous flight...

The stratospheric airship, which is a new concept of autonomous atmospheric flight platforms, can operate over a period of time at very high altitudes to accomplish various military or commercial missions, such as monitoring, surveillance, and scientific exploration. The worldwide interest in stratospheric airships is still growing. However, modell...

This article is concerned with both consensus and coordinated path-following control for multiple nonholonomic wheeled mobile robots. In the design, the path-following control is decoupled into the longitudinal control (speed control) and the lateral control (heading control) for the convenience of implementation. Different from coordinated traject...

This article addresses the robust fixed-time stabilization control problem for generic linear systems with both matched and mismatched disturbances. A new observer-based fixed-time control technique is proposed to solve this robust stabilization problem, provided that the system matrix pair (A,B) is controllable. The ultimate boundedness of the clo...

This paper proposes a robust three-dimensional (3-D) path-following controller for an under-actuated stratospheric airship in the presence of uncertainties. The resultant control system exhibits an inner-outer loop control structure. In the outer control loop, the path-following error dynamics is constructed in a moving Serret-Frenet frame and a ne...

This study studies the output tracking control of a class of sandwich-like systems with state-dependent deadzone non-linearity between two cascaded subsystems (e.g. the gear transmission systems). An exact differentiator-based backstepping control for such a sandwich-like non-linear system is proposed. The proposed controller utilises the high-orde...

... For ground orchard sprayers, a number of studies have shown that targetspecific profiling variable sprays are used to adjust the profiling mechanism of the profiling sprayer to match the contours of the tree canopy [39][40][41][42]. However, due to space and load constraints, UAVs cannot carry heavy equipment [43]. Therefore, in order to achieve precise Drones 2023, 7, 57 3 of 24 ...
... As a special lighter-than-air vehicle, the stratospheric airship is developed to operate in this zone for a long period; thus, it is called "stratospheric satellite." Compared with space-based satellites, the stratospheric satellite is capable of maneuvering to arbitrary positions without the restriction of orbit and has a shorter delay in receiving and transmitting signals [4]. Therefore, the stratospheric satellite performs better performance in aerial photography, scientific exploration, broadcasting relays, and remote sensing missions, to name just a few. ...
... The dynamics of mobile robots may be subject to nonholonomic motion constraints, leading to a challenging controller design. For multi-robot systems (see Fig. 2 as an example), a consensus-based path-following strategy is proposed for multiple nonholonomic robots [87], while consensus for shifted states is achieved to build a group formation among robots [88]. Furthermore, finite-time cooperative control is explored for nonholonomic multi-robot systems [89]. ...
... Compared with finitetime consensus, fixed-time consensus control has greater robustness and gives an analytical expression of the settling time independent of initial conditions. Thus, more and more control schemes are established to realize the fixed-time control problem [25][26][27][28]. For example, based on a class of special auxiliary matrices, a fixed-time synchronization problem of coupled neural networks is resolved in [26]. ...
... Owing to the rapid development of solar energy and material technology, the stratospheric airship has become a research hotspot in recent years thanks to its ability to perform tasks aloft or hovering around a specified area at the altitude of around 20 km [2]. Control research on the stratospheric airship includes path following [3,4], trajectory tracking [5,6], station keeping [7][8][9], formation tracking [10][11][12], and so on. As a high-altitude platform that can perform tasks in a fixed area for a long time, the demand for area coverage control is very strong. ...
... On the other hand, for a gear transmission system, which includes an elastic dead-zone, the back-stepping controller cannot be applied straightforward. Therefore, the system was first converted into two cascaded subsystems; then, the adaptive back-stepping control method was employed to achieve tracking control [22]. Moreover, using adaptive back-stepping control with an approximate smooth backlash model and certain well-defined functions was proposed in [23]. ...
... In contrast to the existing works, e.g., [22]- [24], we mainly focus on the sandwich-like systems with two linear dynamic blocks subject to parametric uncertainties. It is worth mentioning that, in the recent work [35], the output tracking control of a class of sandwich-like nonlinear system is achieved. However, the deadzone parameters used in the control design need to be known exactly, which is usually infeasible to be satisfied in practice. ...
