| dc.description.abstract | Karnaugh map is a method to simplify a logical equation, or convert a truth table in the corresponding logic circuit. This paper presents an alternative way to use the Karnaugh maps that minimizes the logical conditions of command for pneumatic circuits, whether the command is pneumatic or electric. In the last case, the method also permits the control of the circuit through a programmable controller (PLC). In practice, ensure a series of sequential movements in an automatic cycle is to find the set of equations which are executed ensure the realization of the desired sequence. The application of the method itself becomes dispensable analysis of speed or course of the cylinders (irrelevant features to the materialization of the command sequence). It means therefore that the control cylinders equations that will allow his movements (called output variables) are function only of two types of variables (input variables), the position of each cylinder (end-of-stroke valves) and if necessary memory variables. The proposed methodology ensures not only the desired sequential cycle, as well as the minimization of the variables necessary for control commands. To simplify substantially the explanation of the method, it is assumed that each pneumatic cylinder is associated with two end-of-stroke valves for detecting its position. The description as well as the applicability of the proposed methodology will be illustrated using a concrete problem of industrial automation. The methodology described here, will extend its use not only in industrial applications, but also the educational level in terms of engineering schools allowing a particular use in the automation of laboratories in the field of pneumatic control circuits and sequential electro (it is currently teaching in automation course unit of mechanical engineering in ISEP). | pt_PT |
