The paper deals with an emerging problem of AC to DC power converters: the establishment of the mean value of the rectified voltage. This is a difficult task due to the nonlinear behavior of the capacitor filter, attached to the rectifiers. Are proposed novel, simplified mathematical models both of the controlled and uncontrolled rectifier, useful in analysis and design stage. A software product is...
Industrial chemical processes are usually very complex, making the control a challenging task. The 13C isotope separation process is highly nonlinear, with slow dynamics and large time delays. Based on previous research and by experimental knowledge it was determined that secondary processes, like boiler carbon monoxide level or condenser liquid nitrogen level, play an important role in the satisfactory...
The goal of this paper is to present the advantages of robust control in comparison with classic control techniques. Pulse amplitude modulation induction heating inverter with series resonant load circuit with uncertainties is presented for heating nonferrous metals. Inverters performance with robust and PI control will be compared.
