Stability of induced motions in pulse width systems with modulation of the second kind

The motion of pulse-width systems of the second kind with a constant width of output pulsed of the pulse width element, which occurs in static systems with a constant and in astatic system with a linearly increasing input signal is studied. A matrix of a linearized equation of the disturbed motion is determined which makes it possible to assess stability of undisturbed motion with a constant pulse width.
