The purpose of this work is to synthesize the laws for controlling the position of the piston of a pneumatic cylinder using the synergetic method of analytical design of aggregated controllers (ACAR), which takes into account the nonlinear dynamics of the system under consideration. The procedure for the synthesis of synergetic control is based on the introduction of a sequence of invariant manifolds, proceeding from the technological problem of positioning the pneumatic cylinder rod at the required position, and the subsequent step-by-step dynamic decomposition of the original dynamic system. As a result, the synthesized nonlinear two-channel regulator moves the pneumatic actuator rod to a predetermined position while simultaneously stabilizing the pressure in the drain chamber. Simulation of the system with a regulator showed that the control law obtained in analytical form moves the pneumatic actuator rod to a given position while simultaneously stabilizing the pressure in the drain chamber. The paper deals with practical research that was carried out at the educational and experimental stand of pneumatic drives for vertical and horizontal movement of the Camozzi company.
