Abstract
Pneumatic drives in comparison with other types of drives have a large number of advantages: it is the simplicity of design and maintenance; insensitivity to overloads; the availability of air used as a working fluid; environmental friendliness, etc. The article presents a non-linear mathematical model of the pneumatic system, which consists of the equations of the dynamics of the piston, as well as the equations of pressure formation in the chambers of the pneumatic cylinder. Existing methods for controlling such systems are considered. The synthesis of the laws of control by the AKAR method is carried out, graphs of changes in the phase coordinates of the system and control actions are also presented. A comparative analysis of a nonlinear synergetic controller and a linear and nonlinear PID controller obtained by the classical method of typical controllers is presented.Pneumatic drives in comparison with other types of drives have a large number of advantages: it is the simplicity of design and maintenance; insensitivity to overloads; the availability of air used as a working fluid; environmental friendliness, etc. The article presents a non-linear mathematical model of the pneumatic system, which consists of the equations of the dynamics of the piston, as well as the equations of pressure formation in the chambers of the pneumatic cylinder.
