Concept, circuit diagram and algorithm for controlling multi-position pneumatic actuator with adaptive positioning mode

Abstract

The article is devoted to the development of the concept of adaptive control of a pneumatic actuator with the learning mode, a pneumatic circuit diagram and a mathematical model of a relay-operated multi-position pneumatic actuator. With the resulting pneumatic circuit there is no need in using throttle braking any more; the mode of operation of the pneumatic engine can be controlled only by changing the structure of switching connections. Thus, the most favorable uniformly decreasing braking mode can be created, even with significant inertial loads. The described control algorithm based on the obtained pneumatic circuit enables effective implementation of a learning program of the pneumatic actuator.
