NONLINEAR DYNAMICS OF JOY-STICK CONTROLLED MACHINES

Abstract

In practice,joy-sticks are often used when a human operator controls the motion of a machine. The control system provides a kinematical constraint for the controlled machine, i.e the position of the joy-stick determines the velocity of the machine with a certain gain. The human operator, of course, tries to control the joy-stick position in a way that the machine will reach the desired position. The nonlinear mathematical model of this system is analyzed in the paper which also involves the human operator's reflex delay.
