MODELING THE STATISTICAL CHARACTERISTICS OF A MEMBRANE PNEUMATIC VALVE IN MATLAB

To create static models of actuators, linear or polynomial equations are used. Such models do not provide the necessary accuracy for the entire system, although they give an adequate result in a specific area of the process under consideration. In addition, the technical values of the coefficients in polynomial equations cannot always be explained. Analytical modeling of the static characteristics of the object allows us to analyze the influence of the parameters of the object on the overall model. After the model structure is built, the experimental determination of its coefficients ensures that an adequate model can be achieved faster. In this work, a static model of a membrane pneumatic actuator is constructed by the analytical method. The coefficients of the model parameters were determined experimentally. The model and actual results of the process were comparatively analyzed
