✦ Synopsis
An example illustrates algorithms' applicability. 035 Pneumatic Posltioner with Fuzzy Control G. Belforte, T. Raparelil, M. Velardocchla, pp 229-234 the A pneumatic positioner with closed-loop fuzzy logic control is described. The system consists of a pneumatic cylinder, two proportional valves, a position and speed sensor, a fuzzy controller and an A/D-D/A conversion board. No braking devices are provided. The control considers position error and actuator speed as antecedents, and valve control voltages as consequents. Membership functions, the set of rules and the weights of each were obtained. Experimental tests were carried out with different reference signal shapes and different applied loads. Results show good positioning accuracy and repeatability, absence of overshoot and system stability under varying operating conditions.
