In this paper, a path planning method is developed for co-loading in master-slave automatic harvesting. It is shown that, the adjustment of the unloading port position relative to the grain tank can be performed jointly by the longitudinal relative position between the vehicles and the angle of the unloading arm. Then the loading path based on the Hamiltonian circuit is designed to guide the motion of the unloading port during the loading process. By improving the loading uniformity, the loading path proposed can maximize the capacity utilization of grain tank which can reduce the round-trip frequency of the transport vehicle and improve the energy and time efficiency of the harvesting operation. Simulation results are provided to validate the excellent performance of presented path planning method. © 2023 IEEE.

In this paper, a novel adaptive terminal sliding-mode control (ATSMC) method is developed for road vehicles with uncertain dynamics. It is shown that the designed adaptive laws can recursively update the controller parameters based on the estimation values of the unknown parameter bound in the Lyapunov sense, and then the lateral position error can be driven to zero in a finite time. In comparison to the conventional sliding-mode-based vehicle lateral control method, the proposed ATSMC not only ensures fast error convergence, but also eliminates the requirement for known bounded information in controller design. Simulation results are presented to demonstrate the good performance of the proposed ATSMC scheme. © 2023 IEEE.

Sleep is an essential element for achieving well-being. The Rocking Phenomenon has been shown to improve sleep quality and sleep onset, and the vestibular system has been shown to mediate this effect. Rocking is often performed on a rocking bed, which is large in size. The lying body needs to be rocked up and down or right to left side in order for the rocking phenomenon to occur. A large device is needed to rock the body of an adult. Therefore, existing studies have used a method of rocking the bed from right to left side. However, the rocking phenomenon only requires the stimulation of the vestibular organs, which are the sensory organs of the human body. Therefore, it may be possible to produce the rocking effect by rocking the pillow. Therefore, we conduct a one-hour napping experiment to confirm whether rocking of only the head can induce the rocking effect. The results show that delta wave tends to increase and RMSSD becomes smaller as the respiratory frequency is prolonged. We will conduct an all-night experiment to verify the structure of sleep changes even during long periods of sleep. © 2024 IEEE.

In the paper the problem of modeling of thermal processes in microcontroller system is addressed. The proposed models allow to describe thermal processes during work of an evaluation system. The temperature in critical places of the system is measured using thermal camera. The proposed models have the form of hybrid transfer functions, containing both Integer Order (IO) and Fractional Order (FO) parts. The step responses of the proposed transfer functions are computed analytically. Results of experiments show that the proposed models are more accurate in the sense of Mean Square Error (MSE) cost function than typical transfer function models with delay. The proposed models can be applied to predict of overheating of microcotroller systems. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

Impact of the Air Supply System Configuration on the Straw Combustion in Small Scale Batch-Boiler - Experimental and Numerical Studies

Straw-fired batch-boilers use biomass fuel in the form of bales which are autothermaly gasified and burned out in two separate chambers. Among the advantages of such boilers, the most important are construction simplicity and durability, as well as very low payback time when applying wastes from agricultural production as a fuel. Unfortunately, the relatively low energy density of the straw bales determines the extensive dimensions of the chambers. This fact and the unfavourable fuel properties result in difficulties in process control. One of the possible ways to stabilise pollutant emissions and boiler efficiency is to inject the secondary air into the secondary combustion chamber at the appropriate altitude. This paper describes the experimental studies employing the full-scale boiler prototype and numerical modeling of the boiler construction variants incorporating three different positions of the secondary air inlets. Both experiments and CFD simulations allowed to determine the stages of the combustion cycle and to identify the relation between the secondary air inlets' location and the process parameters, such as gaseous pollution and boiler efficiency. Furthermore, simulations allowed to observe the relation between the air supply system construction and the rate of straw burnout. © 2023, The Authors. All rights reserved.

In the paper the numerical estimation of the internal positivity of the model of a two dimensional heat transfer process is addressed. The considered thermal process is described by the fractional order state equation, derived from parabolic heat equation with homogenous Neumann boundary conditions and distributed control and observation. Two numerical algorithms of the positivity testing are proposed and compared. The first one consists in the full examination of the whole area. The next one uses Monte Carlo method. From tests it can be concluded that the considered model can be internally positive only for its lower orders and heating and measurements located closely to the corner of the tested area. The use of the Monte Carlo method allows to significantly shorten the duration of computations. The presented results can be useful in measurements using a thermal camera. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

We consider the system of a beam with a scatterer attachment, where the scatterer can be of either of three types of mass-spring configuration. We explore the vibration response of the beam and the scatterer, aiming to identify special dynamical and scattering responses, for example a pinned point for the beam, full reflection or full transmission, and relate them to the dynamic properties of the scatterer, represented by its impedance. We observe that at the nominal resonance frequency(-ies) of the scatterer, the coupled system presents finite displacement. To further investigate this effect, the vibration response is compared to that of similar forced oscillators, but not attached to a beam, and the similarities and differences are illustrated. It is highlighted that resonances in the forced oscillators do not correspond to resonances in the corresponding systems with the scatterer on a beam. We also briefly discuss how the presence of the beam determines the absence of true resonances in lossless systems. © 2022 Proceedings of ISMA 2022 - International Conference on Noise and Vibration Engineering and USD 2022 - International Conference on Uncertainty in Structural Dynamics.

In this paper, we present a distributed cascade force control system (DCFC) for multiple robots with the aim of pushing a rigid object towards a desired moving target without their inter-robot communication. These mobile robots are equipped with 360-degree vision-based soft tactile sensors utilized to determine contact location and resultant impact force. By investigating the dynamics of moving rigid objects on the flat, we proposed a distributed cascade control. The inner loop control incorporates contact force and positioning, ensuring the robots' pushing contact and applying the desired force to the object. The outer loop control coordinates the robots to push the object in a desired direction without inter-robot communication, regardless of unknown object mass and friction uncertainty. The stability and convergence of the control system are verified using the Lyapunov stability theory. We also conducted simulation and real-world experiments to validate the performance of the proposed control method, and the experimental results showcase the successful coordination of multiple robots in pushing an object towards a moving desired direction. © 2024 IEEE.
