The article presents an industrial application from a plant regarding the automatic movement of some trucks transporting building materials from one sector to another. It presents an alternative solution to conventional control installation of trucks (with electromechanical relays, timers) with a modern control installation made with PLC, static frequency converter, and touch panel.
The paper deals with a mathematical model for airplanes' longitudinal movement during the approach-stage of the landing. One has described an aerodynamic decelerated approach and has established the correlation between airplane's flight commands and thrust level (engines' commands). Airplane's command law was issued (a common law, for rudder and throttle positions), according to the approach law,...
The paper deals with an embedded system consisting of a jet-engine with speed control system (SCS) and a cooling fluid injection system (CFIS), which operates during aircraft's take-off. In order to improve CFIS behavior (which has an independent driven injection pump), it was provided with a flow rate control sub-system (FRC). One has established its new mathematical model and one has also performed...
The present paper has as objective presenting a series of theoretical and experimental research with regards to the automatic control of technological process parameters upon machining by centreless grinding, which is influenced by a series of factors such as that of the variation of kinetic energy.
