Abstract
We consider the problem of the time-optimal turning of a system with two degrees of freedom in the form of a material point on a spring oscillating along a rigid weightless rod that rotates in a horizontal plane. The external control moment is applied to the axis of rotation of the rod and is limited in absolute value; and there is no friction. The problem of the fastest turning of the rod through the given angle from a state of rest with oscillation damping is solved. A feature of a nonlinear system is that its linearized model (in the vicinity of the state of rest) is not controllable.
