Application of digital sliding modes to synchronization of the work of two pneumatic cylinders
The paper considers the problem of ensuring synchronized movement of two pneumatic cylinders. The control system for synchronization was designed by applying the theory of control system with variable structure. The algorithm of control is based on digital sliding regime. Measuring coordinates of state (positions and speeds) directly on the cylinders is supposed to be possible. It is shown that such a system ensures quick synchronization of cylinders under different initial conditions. The applied algorithm was compared with conventional algorithms of control. The quality of work of the considered system was illustrated by computer simulation.
