Analysis of undamped second order systems with dynamic feedback
Remarks about energy transfer in an RC ladder network
The problem of energy transfer in an -ladder network is considered. Using the maximum principle, an algorithm for constructing optimal control is proposed, where the cost function is the energy delivered to the network. In the case considered, optimal control exists. Numerical simulations were performed using Matlab.
Ergodic theory approach to chaos: Remarks and computational aspects
We discuss basic notions of the ergodic theory approach to chaos. Based on simple examples we show some characteristic features of ergodic and mixing behaviour. Then we investigate an infinite dimensional model (delay differential equation) of erythropoiesis (red blood cell production process) formulated by Lasota. We show its computational analysis on the previously presented theory and examples. Our calculations suggest that the infinite dimensional model considered possesses an attractor of a...
Modeling heat distribution with the use of a non-integer order, state space model
A new, state space, non-integer order model for the heat transfer process is presented. The proposed model is based on a Feller semigroup one, the derivative with respect to time is expressed by the non-integer order Caputo operator, and the derivative with respect to length is described by the non-integer order Riesz operator. Elementary properties of the state operator are proven and a formula for the step response of the system is also given. The proposed model is applied to the modeling of temperature...
Applications of mathematics in selected control and decision processes
Rapid development of computer science in recent years allowed more detailed analysis and synthesis of control systems for complex processes and supports decision making in different practical areas. Discoveries in mathematical nature of the universe stimulate representatives of technical sciences to actions leading into planned affecting of real objects. Practical verification of engineers ideas in many cases is effective and leads to meaningful results. In control of dynamical systems the following...
