The paper presents hierarchical control system of air-conditioning process with recycle. Technological demands require changes of the operating points which are realized by the upper control layer. Operating points are optimized using grey box model of the process: one part of the model is formulated as first principle model while the second is identified as the mathematical model. Dedicated optimization algorithm is derived and described in the paper. Direct (lower) control layer uses gain-scheduled PID controllers. This hierarchical control system has been tested on a pilot air-conditioning process which is aimed to verify real-world installation of air-conditioning for the hall where creep testing of metals is performed.

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.

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.

When designing the control algorithm in motion systems, it is not always possible to apply the theory of linear control systems directly. The reason may be a non-linearity of a load, variation of drive parameters, or their lack of knowledge. In this case the solution is the use of adaptive systems. The paper describes an algorithm that combines the IP control scheme and the Model Reference Adaptive Control (MRAC) to adjust the controller parameters and to identify the motor parameters in real time. The proposed solution does not require initial setting of controller parameters. Features of the proposed algorithm are verified by simulations and the results are presented in the paper. Designed MRAC IP controller is suitable for practical implementation in DC and AC drives.

This paper is devoted to the measurable disturbance rejection problem in Generalized Predictive Control (GPC) using an adaptive GPC controller, which combines the process of online system identification and the process of generalized predictive feedback controller design. In this work, the GPC algorithm is extended to the case when the measurable disturbances are available for feedforward control. The proposed adaptive GPC algorithm with/without future disturbance compensation is implemented in real time and experimentally demonstrated for the application of motor revolutions tracking when subjected to deterministic and pseudo-random disturbance signals. The constraint handling capabilities of the controller are considered as well.

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.

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.

In this paper we propose an unconventional approach of remote laboratory development based on industrial hardware. We show that it can significantly reduce implementation effort required for deployment of online labs in control education environment. The hardware architecture of laboratory is based on two devices: a programmable logic controller and an industrial router device, which provide the communication and management capabilities between users and experiments. Using these, we were able to develop operationally effective on-line laboratory for remote control of educational experimental plant in the different way that can be seen in traditional approaches based on standard server computers. On this architecture, we have developed the instance of remote laboratory with highly versatile user interface, based on common Web technologies and powered by optimized JavaScript logic. To prove the architecture suitability, we show the practical case of remote laboratory implementation for control education purposes. In section II, we describe the hardware architecture. In section III, the principles of communication between clients and experiment are given. Overview of laboratory is shown in Section IV and security issues are discussed in section V. An example of experimental usage from student's point of view is given in the last section of paper.
