Abstract
In this paper, a synthesis of a modal regulator for a DC electric drive is performed, described by a linear dynamic model given by equations in the state space. The scientific novelty lies in the reasoned choice of the location of the real poles (p1=-4, p2=-5, p3=-6), which guarantees an aperiodic transient process with a control time of 1 s. The possibility of modal control based on the controllability criterion is proved. The practical significance of the work is to develop a method for eliminating static errors using the Ackermann formula (scaling factor km = 2.67) without changing the dynamic properties of the system. A block diagram has been constructed in the MATLAB/Simulink environment, and the transient characteristics of a closed system have been obtained and analyzed. The results confirmed the achievement of zero overshoot and zero steady-state error.
