Design Algorithm for Sequential Pneumatic and Electropneumatic Systems




pneumatics, automation, control, processes, sequences, complexity


This article presents an alternative automation algorithm for pneumatic sequences that enables the solution of complex sequential problems without the need to organize detection phases into groups. By not using groups to organize movements in detection phases, two benefits can be achieved: firstly, all the drawbacks associated with using groups are eliminated, such as design complexity, difficulty in debugging, increased cost, and difficulty in optimizing the circuit; secondly, it enables the use of logical functions to define each motion in pneumatic actuators. This opens up the possibility to solve logical functions using Boolean algebra techniques, and even their generalization into an algorithm that can be programmed in any language. To validate the proposed algorithm, MATLAB pseudocode is presented. This pseudocode allows obtaining the logical functions needed to build the ladder diagram of any sequence involving up to four double-acting cylinders with any number of phases in a work cycle.
