“…Although in practice, it is difficult to measure wind for small aircraft, by using suitable estimation techniques [12], it can be approximated and used to gain advantage in the perching maneuver. The aircraft can be steered opposite to the wind direction to achieve perching with reduced spatial requirements.…”

This work develops a method for onboard estimation of wind field with spatial and temporal variation based on local wind vector estimation and/or measurements from multiple aircraft flying in the same airspace. Aircraft flying in the same airspace of operation are considered airborne wind sensors scattered over the airspace because of the fact that aircraft carry along with them wind information inherent in their dynamics and kinematics. The onboard wind field estimation is formulated in the framework of parameter estimation based on various wind field models, which are different function of position and time. The online wind field estimation is utilized in trajectory prediction of aircraft flying in spatially and/or temporally varying wind. Various simulation cases are presented to demonstrate the feasibility of wind field estimation and the benefit of using such information in trajectory prediction.

For tracking control issues of distributed electric-driven agricultural vehicles in the complex road conditions driving state, a 6-degree-of-freedom model of agriculture vehicle was established. On this basis, a mathematical model for control system design was derived using the significant advantages of real-time online estimation of vehicle yaw angular velocity of nonlinear third-order extended state observer. Based on the nonlinear third-order extended state observer, a fast and smooth terminal sliding mode control algorithm was designed using the mathematical model. Afterward, the stability of system was analyzed based on Lyapunov theory. The control algorithm used the fast and smooth terminal sliding mode control instead of the normal terminal sliding mode control required control coefficient matrix inverse calculation, which improved the real-time of the control algorithm. Meanwhile, the smooth sliding mode approach law could converge to the sliding surface in finite time and effectively eliminate chattering, and it had strong adaptability to perturbation and perturbation of system parameters. Simulation and experimental results showed that compared with the traditional nonlinear feedback control algorithm based on nonlinear third-order extended state observer, the proposed control algorithm had short adjustment time, small overshoot and good tracking control accuracy.
