Although it is long since the first PID controller design method was developed, new methods are still being created and no general applicable method has been found. The paper extends the set of designing methods of PID controllers. Design methods can be divided into classic (analytical tuning methods, optimization methods etc.) and not so common fuzzy knowledge based methods. In this case, a conjunction...
The paper deals with measurement of concentration of highly toxic carbon monoxide within the space of waste rock storage. This purpose gave origin to creation of units with integrated sensors of carbon monoxide that transmit measured concentration by means of wireless IQRF technology. The need of decreased power consumption implicated choice of electrochemical CO sensor connected to a special wireless...
This article describes the algorithm for searching the human face by the camera. This device is placed in a robotic head. This head should be used for the submission of information when entering into a building such as e.g. a museum. It is therefore necessary for the head to react to the stimuli. If a person appears in front of the head, the head must look at the person and react to the person. The...
This paper deals with the description of pilot operational work of the system for heat energy collection from thermally active mining dump Hedvika. It describes particular technologies for heat collection including the system for use of the gathered heat energy in the form of hot water. It also describes the measurement system that monitors thermal activity of the mining dump at the location of heat...
The paper deals with design of deadbeat controller, particularly with finite time optimal control and quadratic optimal control. It gives a mathematical background for both cases, then it presents case studies with the results and end with the sources codes for Matlab+Polynomial Toolbox.
The paper deals with analysis of case study concerning dynamic optimization problem using Dynopt Toolbox. Particularly it focuses on problem with free time and free end point represented by example of guided missile control in two alternatives. The paper introduces Dynopt as powerful tool for most type of dynamic optimization problem, describing the way how the problem is formulated to be ready for...
The paper deals with the modeling and prediction of thermal processes occurring in the old mining dumps in the Ostrava region. In this region there are many places that arose as a result of long-term mining industry in the past time. One of the most affected mine dumps is the Hedvika mine dump. Hedvika was founded around 1910 and registered in the end of the 50's, and since this time mining dump has...
The paper deals with design and implementation of LQR controller for physical model of inverted pendulum. It presents derivation of the full nonlinear mathematical model, its linearization leading to linear state-space description. The mathematical model is then used for design of LQR controller using Matlab. The control scheme is implemented in PAC (programmable automation controller) WinPAC-8000...
The paper deals with the description of the control circuit of the power plant output superheater. Presented control circuit is modeled based on documentation provided by a power plant operator. Its verification is done through testing the mathematical model with real measured operational data. Output power plant superheater is described by a set of partial differential equations of the first order...
The paper deals with modeling and simulation of the heat exchanger by means of finite difference method (FDM) and finite element method (FEM) in C# and Comsol Multiphysics environments. It refers to previously published papers on this problematic while introducing new approaches. The paper brings a short introduction of solution of above mentioned particular approaches in Comsol Multiphysics and C#.
The paper deals with simulation of both dynamics and control of power plant superheaters by means of Simulink S-functions. Superheaters are heat exchangers that transfer energy from flue gas to superheated steam. A composition of superheater, its input and output pipelines, and fittings is called a superheater assembly. Inertias of superheater assembly are often decisive for design of a steam temperature...
