International Conference on Process Control

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 on-line 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.

A basic control course is taught for electrical engineering students at the University of Debrecen, Hungary. Through two semesters the students get a basic knowledge on control concepts. Every week there are 2 hours of theoretical lectures immediately followed by 2 hours of MATLAB based interactive computer laboratories. In the curriculum besides the conventional material new aspects of control design such as Youla parametrization have also been included. Practical considerations as e.g. controller saturation are also dealt with. The paper reviews briefly the curriculum and the educational process of this program.

This paper addresses the adaptive control design of a semi-active suspension system. The control system is focused on the driving comfort criteria. For this purpose, it is necessary to emphasize on modeling and connection between vehicle suspension system components. On the other hand, we will compare the obtained results using the designed adaptive control system with the optimal control design applying soft and hard suspension. Moreover, a hydro-pulse will be used for road vibration simulation purposes. In this case, the analysis has been performed over the frequency bandwidth 4-20 Hz considering a constant vehicle speed 80 km/h.

International Conference on Interactive Collaborative Learning

Systems of linear differential equations with constant coefficients occur in the area of operations research very frequently. These arise, for example, as mathematical models of dynamical systems. One can solve linear systems using the method of variation of parameters or using Laplace transform. Sometimes, for the given system, both the methods can be used, while in other cases we can solve it only by one of the methods. In particular, if the system is an initial value problem with discontinuous forcing terms we (frequently) have to solve it using Laplace transform. On the other hand, if there are boundary conditions of special types, it is not possible to use Laplace transform. In this contribution we show how to solve it in both cases and we also show that the student of automation have to know both the ways of solution.

International Conference on Process Control

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.

International Conference on Process Control (PC)

Recent developments in the area of industrial programing software expand the potential of the automation programs considerably. In addition to IEC 61131-3 languages, programming languages like C and C++ are getting available for industrial controllers, which opens new possibilities of reusing existing programs for real time processing in these controllers. Paper deals with swing-up and online model predictive control of mechatronic device - reaction wheel inverted pendulum. Swing-up control uses convenient shape of exponential function over pendulum position for determination of required energy to be delivered to the system. For stabilization of pendulum in the upright position a predictive controller based on optimal control law with perturbation was used. An important part of the solution is PLC implementation of qpOASES package for numerical solution of quadratic optimization problem. Application is implemented and tested using industrial PLC connected to a laboratory pendulum.

A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The combined measured mass of the Higgs boson is mH=125.09±0.21 (stat)±0.11 (syst) GeV.

This paper proposes a novel concept of a flexible instrument for minimal invasive robotic surgery. The focus of this snake-like manipulator is to reduce the trauma for the patient and a shorter time of hospital stay. Furthermore the performance of complex interventions will be simplified due to the wide range of instruments degrees of freedom. The mechanism of this manipulator is built of several modular segments, which are linked to each other. The two DC-motors inside the segments submit the required two DoFs for generating a 3d pathway. The design of the mechanical parts, sensors and a concept for the control system will be presented in this paper. A simulation environment with an associated mathematical model is also implemented.
