Opis:: This paper considers the issue of vertical position control of a ball placed on a disc. The aim of this work is to create a fuzzy logic controller able to manage the issue of ball and wheel. The second chapter describes the identification system. In the next chapter a Fuzzy controller is described. The last chapter is dedicated to results of implemented fuzzy controller. Most of control tasks in transport are non-linear. This application should help to apply a fuzzy control in such systems.

Opis:: The tunnel central control system is designed for maintaining the necessary safety and resistance against failures as a system fully redundant at all levels. All hardware components of the control system and their connections are doubled. Control system is based on the programmable logic controllers (PLC’s) and used the industrial buses on an optical and metallic physical layer. This system controls the traffic and all tunnel equipment systems (variable traffic signs, various lighting elements, ventilation system, etc.). Nowadays the control strategy is based on measured data inside the tunnel, metrological information and operator’s commands. The control strategy or algorithm must be enhanced to obtain better or optimal results. Using of model predictive control (MPC) may lead to optimize the control way for chosen criteria. MPC can be implemented to PLC by several methods.

Opis:: This paper deals with models of air pollution inside a tunnel tube. Various gases are emitted by combustion engines. They consist largely of oxides of nitrogen, carbon monoxide, steam and particles (opacity). Since each tunnel is unique, the design of the model must be realized for the particular road tunnel. Data measured in the control center of the tunnel is used to create various models and to realize them in the program environment MATLAB. It is possible to describe this system by description of the equations of physical dependences. These physical dependencies are between the speeds, piston effect, traffic density, quantity produced pollution, etc. Next we plan to show how fuzzy sets can be used to represent a real system. Finally, we are going to describe this system by the parametric model. For the purpose of parametric identification it is interesting to describe the sought process using input-output relations. The general procedure for estimation of the process model consists of several steps: determination of the model structure, estimation of parameters and verification of the model.
