In the paper, the robust control of temperature fields of the casting mould in the benchmark casting plant is presented. Temperature fields of the mould are represented by dynamic models in the form of a finite-dimensional approximation of distributed parameter systems. Models are created by means of an experimental identification. The control synthesis is decomposed to the time and space domain. For the control synthesis with internal model control structure in the time domain, an uncertainty of the controlled system is considered and robust controllers are designed.

One of the key challenges during a disaster is that the activity of rescue and relief has to be well-coordinated. For this reason there is a need for a complex system that will provide facilities for acquisition, exchanging and sharing of immediate information to obtain a better overview of current situation and interactively improve the coordination of the rescue team. his article presents our approach to specific integration of various data sources and information sharing based on collaborative exchange of actual geo-located information, commands or measured data between the stationary or mobile sensor platforms and rescue workers. A role of our unmanned aerial vehicle (UAV) system, used as a valuable source of actual data for crisis management during a forest fire combat, will be demonstrated.

The paper presents a possibility of application a hybrid algorithm compound of a global algorithm Interpolated Ant Colony Optimization and local Directional Derivatives Simplex (IACO-DDS) to identification of the time delays in the linear plant. The Interpolated Ant Colony Optimization algorithm (IACO) can be used to continuous problems. The Derivatives Simplex belongs to the class of a modified Nelder Mead Algorithm. The IACO-DDS algorithm is compared with the simple IACO in terms of their speed and efficiency for unimodal and multimodal search space. The investigation was made for the sixteen plants with random parameters, divide into two group: the simple and difficult to identification plants.

This paper discusses the problem of effective motion planning for industrial robots. The first part dealt with levels of industrial robot planning. Second part discusses the basic principle of path planning. In the third part is presented the work done with one of the simulation system with automatic trajectory generation and off-line programming capability. An spot welding process is involved. The practical application of this step strongly depends on the method for robot path optimization with high accuracy, thus, transform the path into a time and energy optimal robot program for the real world, which is discussed in the last two steps.

Type 1 Diabetes Mellitus (T1DM) subject model is presented in this paper. The model consists of two parts. A glucose and insulin plasma kinetics is inferred from a minimal model of glucose kinetics commonly used to analyze the results of an intravenous glucose tolerance test (IVGTT). A subcutaneous insulin and a subcutaneous glucose kinetics are modeled as a time-delay. A meal announcement information is considered as a measured disturbance signal and a disturbance model is also proposed. The presented model serves as a base for the design of an adaptive control algorithm for automatic normoglycemia maintaining in T1DM subject. The adaptive control algorithm is also briefly presented in the paper.

Current changes to the terms of advanced mechatronic systems (currently in robotic systems) and current intensity of demands on them in practice require new insights into the processes and techniques of designing and verification of the project designs.

The methods of electronic throttle experimental identification together with optimization based parameters estimation are presented in this article . The parameters identified by this experimental identification were used as initial values of optimization variables in the problem of nonlinear optimization, where the cost function was non smooth. For this type of problem the Pattern Search method was used and satisfactory results were obtained. The results in this article are presented in the graphical form and show closeness between the measured and modeled signals of throttle plate position and angular velocity. The results are satisfactory for data, which were measured in closed loop by nonlinear throttle plate position controller.

The paper presents simulation study on control of temperature field of steel billet during continuous casting. The cooling of steel billet is controlled with secondary cooling zone - a set of water jets divided into independent subzones. The temperature field evolution in time and space is described by non-linear partial differential equation. The solution of this equation is obtained numerically, using specialized finite element software ProCAST. Lumped-input and distributed-parameter-output system (LDS) is introduced, with the inputs being cooling water flow rates and the temperature field being the system's distributed output. Control synthesis in the system's feedback is solved in space and time direction. To represent the temperature field during setpoint changes a co-simulation interface was added to the DPS Blockset (Third-Party software product of The MathWorks). The interface block enables you to couple a finite element simulation in ProCAST and control scheme in Simulink. This feature brings you the full power of Simulink to extend the capabilities of finite element simulation.
本文对连铸过程中钢坯温度场的控制进行了仿真研究。钢坯的冷却是由二冷区控制的，二冷区是一组水射流，分为独立的子区。用非线性偏微分方程描述了温度场在时间和空间上的演化。利用专用有限元软件ProCAST，对该方程进行了数值求解。介绍了以冷却水流量为输入，温度场为系统分布输出的集总输入和分布参数输出系统。从空间和时间两个方向解决了系统反馈中的控制综合问题。为了表示设定值变化期间的温度场，在DPS Blockset (the MathWorks的第三方软件产品)中添加了一个联合仿真接口。接口模块使您能够耦合ProCAST中的有限元仿真和Simulink中的控制方案。此功能为您带来了Simulink的全部功能，以扩展有限元仿真的功能。
