Distributed Wireless Mechatronic System Operated from MATLAB-Simulink Environment
Belda, Květoslav ; Rychnovský, V. ; Píša, P.
The paper deals with a realization of control of distributed mechatronic system operated from MATLAB-Simulink environment. The mechatronic system serves as a laboratory model of simple manipulation system. The communication within the system is provided by wireless ZigBee protocol through a coordination unit. This unit is connected via serial interface to the control computer, where appropriate Simulink model runs. The paper addresses briefly individual physical components of the system (units, passive and active or executive elements etc.), specific blocks of used Simulink model and demonstrates the system behavior on several examples.
Impact of forgetting on models of rolling mills
Dedecius, Kamil ; Jirsa, Ladislav
The research report deals with an analysis of various models for modelling of the cold sheet rolling process. It comprises a thorough analysis of a mass-flow model and its weaknesses, brief analysis of normalization impact on modelling and exhaustive analysis of 4 defined models with exponential and partial forgetting and their comparison to models without forgetting. The report ends with a computer-intensive search for new blackbox models.
Self Fine Tuning of LQ Control With Fixed Model
Belda, Květoslav
Setup of suitable weight control parameters and their tuning with respect to topical controlled system behavior is a principal issue of every control design. This contribution roposes the efficient way for setup and tuning of the control parameters of LQ controllers automatically by evaluation of a controlled system response in comparison with a mathematical model following from a physical substance of that system. The controlled systems are considered as stochastic, which corresponds to a stochastic nature of real-life applications. In this paper, there will be explained general assumptions and conditions for the implementation of the proposed way. The theoretical results will be discussed and illustrated by several examples.
