This paper presents an approach intended for tracking of biological non-stationary signals. The proposed approach utilizes a Kalman filter autoregressive model together with a method for estimation of covariance matrices of the uncorrelated process noise and measurement noise. The method was tested in simulations, where the ability of tracking of a class of time varying autoregressive processes was...
This paper deals with the control of the preheating process of a casting mould formulated as a distributed parameter system and using a programmable logic controller (PLC). The control process is first optimized by a simulation procedure using a distributed parameter control loop. The temporal part of the control synthesis is implemented on the PLC in order to control the preheating of the casting...
In the paper, the robust control of temperature fields in the secondary cooling zone of the continuous casting process is presented. Temperature fields are represented by dynamic models in the form of a finite-dimensional approximation of distributed parameter systems. Models are created by means of validated finite element method modelling. The control synthesis is decomposed to the time and space...
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,...
