This article describes an optimal control algorithm for a DC motor drive operating as a positioning system. The control algorithm is based on combination of artificial neural network and state space method with variable gain. The positioning system operating under proposed algorithm has demonstrated a transient process close to optimal without overshoot. It(More)
This paper represents design procedure of control system for interleaved bidirectional dc-dc converter. Dynamic model of the converter was compiled with help of steady-state analysis. The theoretical results were verified by means of modeling in PSIM package.
This paper describes a model predictive control (MPC) algorithm for the interleaved dc-dc bidirectional converter with coupled inductors for Photovoltaic (PV) applications. An averaged discrete state space model of the converter was developed. The main control objective was to regulate the output voltage to its reference value despite changes in the load(More)
We present the calculations of intracavity radiation for a confocal positive-branch unstable resonator with a radially or azimuthally selective mirror. We carried out beam propagation in the resonator by the fox-li iterative method using jones vector calculus for the polarization state. The optimization of the resonator for generating a high-power radially(More)
Optical microscopy and atomic force microscopy were used to study a novel roughness-induced wrinkling instability in thin-film bilayers of poly(ethylene oxide) (PEO) and polystyrene (PS). The observed wrinkling morphology is manifested as a periodic undulation at the surface of the samples and occurs when the bilayers are heated above the melting(More)
Predefined heater parameters are involved in self-tuned temperature control for plastic moulding. However the heater system transfer function depends on many external parameters, such as barrel filling level, type of plastic etc. This paper discusses a recursive least-square estimation of plastic moulding heater parameters identification. The real heaters(More)
