Strip offset can cause registration errors, resulting in a large amount of waste during the printing process. In order to achieve precise control of the running track, this paper designs a correction system controller based on fuzzy PID control strategy. Firstly, the basic principle of the belt transmission is analyzed, and the dynamic model of the belt movement is established. Secondly, The ultrasonic sensor is used as the detection device, SCM is used as the control core and the stepping motor is used as the actuator. Thirdly, a correction system control method based on fuzzy PID control strategy is proposed, and the control system software is developed. Experiments show that the correction controller can realize rectifying control of various types of printing materials and is suitable for a variety of high-end printing equipment. © Springer Nature Singapore Pte Ltd. 2020.

The emission of VOCs (Volatile Organic Compounds, VOCs) during packaging and printing production endangers human health and causes serious pollution to the environment. The regenerative thermal oxidizer is a widely used VOCs processing equipment. In order to fully grasp the law between its structural parameters and treatment effects, this paper numerically simulates the regenerative thermal oxidizer. Firstly, the working principle is analyzed, and the internal structure and 3D modeled are designed. Secondly, the simulation calculation of the regenerator is carried out, and the variation of temperature and pressure inside the regenerator is obtained. Thirdly, according to the simulation results and numerical analysis, the relationship between the pressure drop of the regenerator bed and the bed height, thermal efficiency and bed height under different mesh types is obtained. The results show that when the pore shape and flow rate are the same, the pressure drop is positively correlated with the bed height. The thermal efficiency increases with the increase of the bed height until the thermal efficiency reaches 100%. When the thermal efficiency meets the actual operation requirements, the bed height should be reduced as much as possible to improve equipment utilization. © Springer Nature Singapore Pte Ltd. 2020.

Vehicle platoon is one of the concrete manifestations of multi-vehicle cooperative control and intelligent transportation. However, the velocity perturbation in the driving process will bring about stability and safety problems. The connected autonomous vehicles (CAVs) can obtain the motion status of the lead vehicle in real time and respond to it in time, which is of far-reaching significance to platoon control. Based on this, this paper focuses on the longitudinal driving strategy of connected autonomous vehicle platoons. Specifically, we provide a discrete double-integral model controller for each vehicle in a generic scenario, and the controller performs acceleration and deceleration control at each timeslot according to the state of the vehicle in front and its own state. Simulation experiments are designed by varying the size of the platoon and the number of connected autonomous vehicles. The experimental results show that the introduction of connected autonomous vehicles can effectively suppress the platoon velocity perturbation, increase the stability of the platoon driving, and significantly reduce the fuel consumption at the same time.

The paper presents a comparative study of various ways of specifying program movements for mechatronic objects (MO) along complex spatial trajectories defined by parametric Bezier splines, B-splines and third-order Catmull-Rom splines. An expression is obtained to describe the dependence of the rate of change of the parameter setting the desired position of the MO with the program speed of its movement, taking into account information about the type of trajectory. As a result, using this expression, which is universal for all the specified parametric splines of the third order, it is ensured that the MO moves along the trajectory exactly at a given speed while simultaneously changing its orientation as desired. The application of the methods considered in this paper does not require complex iterative calculations and allows one to perform all the necessary calculations in real time, even on low-power on-board computers of various robots and robotic complexes. Numerical modeling was carried out to analyze the features of the use of these splines in solving practical problems.

IEEE/RSJ International Conference on Intelligent Robots and systems (IROS)

Hardware-in-the-loop simulation (HILS) allows a more realistic evaluation of control approaches than what is possible with pure software simulations, but without the actual complexity of the complete system. This is important for some complex systems such as orbital robots, where testing of the system is typically not possible after its launch, and an on-ground replica is used to validate the performance of such a system. In this article, an impedance-matching approach is presented to match the end-effector dynamics of a fixed-base robot manipulator with that of a target vehicle-manipulator system (VMS), while taking into account the redundant nullspace dynamics in a connected real-time simulation framework. This approach ensures that the forces and torques exerted by the system on the environment matches with that of the simulated system. The contact wrenches used in our approach are not obtained from numerical simulations, but rather from real physical interaction, which is one of the main advantages of our approach. The effectiveness of our method is validated by demonstrating various physical interaction tasks with the environment, using a suspended aerial manipulator as the target system.

We propose a Multi-Agent Phasic Policy Gradient (MAPPG) algorithm, which can assist agents to further alleviate the non-stationarity of the environment. Different from the existing methods, the auxiliary phase is introduced to train the local policy directly by using the environment state, which can be naturally integrated into other algorithms. Specifically, the hidden layer feature sharing is proposed, which ensures feature sharing between the global value network and the local policy network for the first time. Meanwhile, mirror descent is utilized to iteratively update the policy in the auxiliary stage, which makes the policy update more robust. Through a series of evaluations on multi-agent Particle and multi-agent Mujoco benchmark environments, the experimental results show that our method achieves higher rewards than state-of-the-art benchmarks.

Explosive synchronization in multiplex neuron-glial networks

Explosive synchronization refers to an abrupt (first order) transition to non-zero phase order parameter in oscillatory networks, underpinned by the bistability of synchronous and asynchronous states. Growing evidence suggests that this phenomenon might be no less general then the celebrated Kuramoto scenario that belongs to the second order universality class. Importantly, the recent examples demonstrate that explosive synchronization can occur for certain network topologies and coupling types, like the global higher-order coupling, without specific requirements on the individial oscillator dynamics or dynamics-network correlations. Here we demonstrate a rich picture of explosive synchronization and desynchronization transitions in multiplex networks, where it is sufficient to have a single random sparsly connected layer with higher-order coupling terms (and not necessarily in the synchronization regime on its own), the other layer being a regular lattice without own phase transitions at all. Moreover, explosive synchronization emerges even when the random layer has only low-order pairwise coupling, althoug the hysteresis interval becomes narrow and explosive desynchronization is no longer observed. The relevance to the normal and pathological dynamics of neural-glial networks is pointed out. © 2023, CC BY.

Complex economic models often describe the agent's decisions, i.e. choice of some controlled variables in accordance with criteria set by agents. Unlike purely statistical ones, agent-based models allow to describe processes with different modes, in which the agent's behavior changes quali-tatively when the environment (including the actions of other agents) change. The practical use of mathematical models of complex systems with a number of interacting agents is limited by complexity of their construction and possible errors when dealing with multitude of expressions. Computer tools, such as the 'Ecomod' system discussed in the article, can substantially reduce the time spent on model creation and processing, and help to coordinate the work of several researchers on the model. © 2023 IEEE.
