Abstract
This paper presents modeling, simulations and control of the ground-to-air missile fin actuation system, where brushed DC motors are used as actuators, which are driven using voltage regulation-Pulse Width Modulation (PWM). The mathematical model of the system was determined using the differential equations of behavior of the lowest order that was experimentally confirmed. This model was taken as a starting point in the synthesis of the Lead compensator, used to regulate the position of the missile's control surfaces. The trial and error method was used for the synthesis of Lead compensator, taking care to meet the required characteristics of the System, in form of bandwidth and gain. The improved transient process and behavior of the System have also been experimentally confirmed.
