Based on the analysis of longitudinal control scenarios, a longitudinal control model of the intelligent vehicle in virtue of hybrid automata is built. Driving situations are divided into cruise control, speed following, inter-vehicle distance adjustment modes. Three corresponding control strategies are proposed depending on the driving modes. Then an algorithm of the longitudinal controller is designed. Not only is the following control of the target vehicle in the same lane achieved, but also, when the target vehicle changed, the following control of the new target vehicle is achieved through the control strategies of inter vehicle distance adjustment. Simulation results show that the designed strategy can achieve a variety of scenarios in both highspeed driving and low-speed stop-and-go situations.

Temperature field control system of the autonomous object of support structure with the information-measuring system is introduced. To compensate the thermal deformation of the structure due to the temperature field irregularity, caused by heating of information-measuring system elements, the control algorithm has been proposed for controlled heat-sources which are specially placed on the structure. The simulation in program software environment ANSYS shows high efficiency of the presented algorithm and management system.

This paper proposes a modular redesign of multi-armed robotic systems with application to in-orbit operations. The manipulators that the robot includes are made independent and the connection to the central body is achieved through additional standard interfaces (SI). This grants the system the ability to self-repair through self-reconfiguration. The arms are also upgraded, giving rise to symmetrical manipulators of 7 degrees of freedom (DOF) capable of locomoting by themselves. The models of the new manipulator design are presented along with its nominal workspace. In addition to this, a novel algorithm for the control of the arm is developed based on the FABRIK approach. This programme is tested using diverse target poses as input and the consequent results are shown too. All the models and sketches were created in SolidWorks;the algorithm was coded in MATLAB.

In this paper, a control architecture merging a Reference Governor and a Model Reference Adaptive control law is tested on a high-fidelity Simulink model of a Parrot Bebop 2 Drone. This system is considered to be subject to velocity constraints, and the flight simulations are performed in the presence of simulated matched uncertainties to recreate the typical uncertain environment in which a drone operates. The proposed control framework allows for precise tracking and constraints enforcement despite the uncertainties and the perturbations acting on the system. The novelty of the approach consists of exploiting the adaptive law performance to build a robust Reference Governor with limited conservatism. As a result, larger uncertainties can be handled, and the computational complexity of the governor's optimization problem is limited compared to the standard robust Reference Governor strategy.

We present a new technology for real-time walking of a biped robot. A biped robot necessitates achieving stabilization for real time walking since it has basic problems such as structural stability. In this paper, a robust control algorithm for stable walking is proposed based the ground reaction forces, which are measured using force sensors during walking, and the environmental conditions are estimated from these situation. From this information the robot selects the proper motion and overcomes ground irregularities effectively. In order to generate the proper angel of the joint. The performance of the proposed algorithm is verified by simulation and experiments for a 20-DOFs humanoid robot.

In order to realize the remote control of the meeting documents in progress, the traditional method uses infrared remote control or 2.4 GHz wireless remote control. However, the shortcomings of carrying and storing the remote control, the infrared itself cannot pass through obstacles or the remote control of the device from a large angle, the 2.4 GHz cost is slightly higher, etc., this article introduces the use of PyTorch model and YOLO network gesture control to facilitate this practical problem. The plan proposes to use the PyTorch model to establish a neural network, train to achieve the purpose of classifying gestures, and use the YOLO network to cooperate with the corresponding control algorithm to achieve the purpose of controlling conference documents. The experimental results show that the proposed scheme is feasible and complete to achieve the required functions.

NASA's Dragonfly mission, led by The Johns Hopkins University Applied Physics Laboratory, is a relocatable octocopter lander to study Saturn's largest moon Titan. The scientific goals of the mission include studying Titan's prebiotic chemistry, geology, and atmosphere. Upon Titan arrival, the lander will enter the atmosphere, descend on a parachute to a ground-relative altitude of about 1000 m before being released, and then fly on internal power down to the surface. To guarantee desirable initial conditions for the lander release, the lander must meet certain angular rate conditions. These conditions include reducing the spin rate about the vertical axis to 4.9 deg/sec, using the rotors as actuators;and releasing with a negative pitch rate (rotating nose down) to ensure a successful transition to powered flight. This is achieved using a release trigger. Achieving these desired rates for lander release is part of the mission phase known as 'preparation for powered flight' (PPF). This paper presents the control algorithms and logic developed to achieve the desired conditions for releasing the lander from the backshell and parachute.

A novel Open-winding Permanent Magnet Synchronous Motor (OW-PMSM) drive system based on the five-leg inverter is presented to reduce the cost, volume and the switching loss of the inverter. Due to the common DC bus of the proposed five-leg inverter, the zero sequence current generated by the inherent 3rd harmonic of the phase back EMF flows through the phase windings and it leads to the weakness of efficiency and torque triple to the drive system, therefore, the closed-loop of zero sequence current and modulation method of the five-leg inverter were employed to the system control strategy and it generated the offset 3rd back EMF to suppress the zero sequence current. The double-loop control algorithm for the proposed OW-PMSM drive system was realized by the software of Matlab/Simulink, and the validity of the high performance OW-PMSM drive system based on the five-leg inverter was verified by the simulation results.

Congestion at motorway junctions is a traffic phenomenon that degrades operation of infrastructure and can lead to breakdown of traffic flow and associated reduction in capacity. Advanced communication technologies open new possibilities to prevent or at least delay this phenomenon, and innovative active traffic management systems have been developed in the recent years for better control of motorway traffic. This paper presents a review of control strategies for facilitating motorway on-ramp merging using intelligent vehicles. First, the concepts of the control algorithms are reviewed chronologically divided into three types of intelligent vehicle: completely automated, equipped with cooperative adaptive cruise control and equipped with on-board display. Then, a common structure is identified, and the algorithms are presented based on their characteristics in order to identify similarities, dissimilarities, trends and possible future research directions. Finally, using a similar approach, a review of the methods used to evaluate these control strategies identifies important aspects that should be considered by further research on this topic.
