The paper presents models and estimation algorithm of the air stream velocities in pneumatic material transport for supervisory and direct control layers of electromagnetic milling system. The algorithm uses redundant measurement system and identifies parameters of the first principle model to increase reliability of the measurements and to give rise of the fault detection system.
The paper presents control system of a working chamber load of an electromagnetic mill. The mill works in a dry grinding and classification circuit with pneumatic transport. Structure of the circuit is presented in the paper as well as the measurement system. Data acquisition uses direct and indirect measurements. The most challenging are the indirect measurement of the chamber fulfillment and the...
The paper presents optimizing control of the electromagnetic grinding system. The electromagnetic grinding is a complex process, thus formulation of the optimization problem is done in a top-down manner. To do so, the parameters which influence product quality and serves as decision variables are specially selected. The selection follows from environmental analysis of the system and discussion of...
The paper presents a model of the air stream ratio in the dry grinding and classification circuit with the electromagnetic mill. The concept of the grinding system is described along with indirect measurement methodology. Model structure and identification problems are discussed and a supervisory control algorithm based on the model is derived.
The paper presents feedback control algorithm for active vehicle suspension systems. The algorithm uses internal model of the system which is composed with two parts: disturbances path and control path. The first is highly non-stationary while the second is constituted with relatively fixed-parameters. This difference justifies the use of limited authority adaptive control, where only disturbance...
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...
Structure choice and identification of stratified models' parameters are presented in this paper. Stratification is suggested to base on the environmental structure of the plant. Algorithm of Generalized Back Propagation Through Time is applied as the identification method. Vertical hot water tank serves as the illustration of application to single dimensional case. Methods of generalization on three...
