A word in defense of the discrete control signal

In the structure of automatic regulators are still widely used astatic electrical constant speed actuators. An alternative solution is the use of electrical constant speed actuators, but the proportional action. The comparative evaluation of the both version of the actuators. Attention is drawn to the importance of determine the amount of time the full move electrical actuators. It is argued that the most accurate way to determine this is to use simulation modeling. The advantages obtained in case to ensure proportionality of the action of traditional electric constant speed actuator.
