Abstract

Un sistema de ascensor que comprende: un camarín de ascensor; medios motores para dicho camarín de ascensor; medios de pauta de velocidad que proporcionan una señal de pauta de velocidad indicadora de la velocidad deseada de dicho camarín de ascensor; medios que proporcionan una señal de velocidad sensible a la velocidad real de dicho camarín del ascensor; y caracterizado por: medios de impedancia controlable; medios de control que proporcionan una primera señal de control sensible a por lo menos un parámetro predeterminado de dicha señal de pauta de velocidad, incluyendo dichos medios de control primeros medios de referencia que proporcionan una primera señal de referencia relativa a dicho al menos un parámetro predeterminado de dicha señal de pauta de velocidad, modificando dichos medios de control la impedancia de dichos medios de impedancia controlable en respuesta a una relación predeterminada entre dicha primera señal de control y dicha primera señal de referencia; unos medios de señal de error que proporcionan una señal de error para controlar dichos medios motores en respuesta a dicha señal de velocidad y a dicha señal de pauta de velocidad; estando conectados dichos medios de impedancia controlable para modificar el efecto de dicha señal de pauta de velocidad sobre dichos medios de señal de error, al menos cuando su impedancia es modificada por dichos medios de control.
