Abstract
Un sistema de posicionamiento que responde a una orden de entrada de posición para mover un miembro a lo largo de una trayectoria de desplazamiento predeterminada entre una posición corriente y una posición de referencia de blanco definida con respecto a dicha trayectoria de desplazamiento en un tiempo mínimo compatible con limitaciones de rendimiento en el sistema, comprendiendo dicho sistema: un accionador eléctricamente operado para mover dicho miembro a lo largo de dicha trayectoria predeterminada en respuesta a señales de excitación eléctricas y que tiene un circuito de entrada al que se aplican dichas señales y medios de control de alimentación directa para proporcionar una señal de excitación predictiva variable con el tiempo a dicho circuito de entrada del accionador para efectuar un control aproximado de dicho movimiento.
