This paper describes a software, developed in PROLOG, called ISEPCPC (Intelligent System for Electric and Pneumatic Control of Pneumatic Circuits). It uses PROLOG clauses, Artificial Intelligence (AI) techniques (an Expert System), and Karnaugh Map’s methodology. The main objective is to compute the set of optimized logic equations that enables either an electric or a pneumatic control of any, but mainly complex pneumatic circuits. As the complexity of the circuit increases, as the result of a combinatorial explosion generated by the increase in the number of cylinders involved, the more difficult it becomes to obtain the control equations (often requiring the use of auxiliary memories). This software automatically obtains the equations which will yield minimized circuit configuration. These equations, can be used either in electro or pneumatic control. A practical application example of the software will be shown to prove its applicability. The minimum number of equations required to control the circuit will be used in programming a PLC that will control the circuit.
