The problem of traffic control is solved using a model-based method. Automaton formalism is proposed for the development of a mathematical model. The states of a deterministic finite automaton (DFA) and the predicates of directed transitions are defined in strict accordance with the conditions of the problem. To implement the DFA, we used the Harel diagram (statechart);this is unified mathematical and software support for modern global modeling tools. The solution to the problem is proven constructively by a table of states with the corresponding dynamics and computational experiments of the selected scenario in advanced Russian and foreign instrumental environments for modeling the class of event systems. Computational experiments are in good agreement with constructive analysis.

Introduction: Nocturnal glucose control remains challenging in children and adolescents with type 1 diabetes due to highly variable overnight insulin requirements. The issue may be addressed by glucose responsive insulin delivery based on real-time continuous glucose measurements. Areas covered: This review outlines recent developments of glucose responsive insulin delivery systems from a paediatric perspective. We cover threshold-based suspend application, predictive low glucose suspend, and more advanced single hormone and dual-hormone closed-loop systems. Approaches are evaluated in relation to nocturnal glucose control particularly during outpatient randomised controlled trials. Expert opinion: Significant progress translating research from controlled clinical centre settings to free-living unsupervised home studies have been achieved over the past decade. Nocturnal glycaemic control can be improved whilst reducing the risk of hypoglycaemia with closed-loop systems. Following the US regulatory approval of the first hybrid closed-loop system in non-paediatric population, large multinational closed-loop clinical trials and pivotal studies including paediatric populations are underway or in preparation to facilitate the use of closed-loop systems in clinical practice.

A humanoid robot motion control system needs to deal with information from encoders, acceleration, force, gyro and vision sensors, etc. and needs to control more than 30 degrees of freedom (DOFs) joints motion. An effective motion control system is necessary for the humanoid robot to complete walk and manipulation. This paper discusses the motion control system architecture, hardware design and control algorithm. According to the requirements of the humanoid robot, a distributed motion control system based on controller area network (CAN) bus is used in the humanoid robot system. Analysing the motion control algorithm, we used integral separation proportional integral derivative (PID) control algorithm to guarantee the humanoid robot to move and manipulate in real-time and precisely. Experiment results show that the proposed motion control system for humanoid robot is reliable and stable, and is adaptive to deal with complex tasks in daily life.

A distributed adaptive control design for an uncertain modular robotic system is proposed in this paper. Specifically, a modular robotic system that consists of multiple robot manipulators that are subject to uncertain non-linear robot parameters and robot-based uncertainties is considered. A distributed adaptive control is designed to compensate for uncertain non-linear robot parameters and robot-based uncertainties, closed-loop system stability analysis is shown via Lyapunov stability analysis, and simulation results are provided on a modular system.

This work addresses the goal of guiding an aerospace vehicle to a particular location in space with a desired heading vector, while simultaneously optimizing an energy cost function. The optimal solution is derived with soft penalties on position and heading error, so the result is applicable to a wide variety of scenarios that have different objectives, and possible limitations on exactly satisfying hard constraints.

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.
