The problem of constructing an element of the unmanned aerial vehicles autopilot that ensures the transfer of an object to the designated state in a finite, minimum time interval is considered. In contrast to existing solutions, the article poses a synthesis problem for implementing control in a digital system, a feature of which is the discreteness of input information. Although the synthesis uses a simplified mathematical model of a system with multiple zero poles, the control algorithm is presented as an alternating function with a switching surface for a triple integrator, which provides no more than two intervals for switching the sign of the control signal. In addition, the conditions for constructing the switching function are analyzed, and a model example is presented.
