Abstract
An actuator provided with a pump connected to a first hydraulic connection connected to a reservoir and to a second hydraulic connection. A command controller communicates with a first pressure sensor arranged on the second hydraulic connection and measuring a first supply pressure. A monitoring controller communicates with the command controller and a second pressure sensor arranged on the second hydraulic connection and measuring a second supply pressure. A virtual pressure sensing device is provided with a verification instrument transmitting at least one verification signal carrying an operating parameter of the pump to the command controller and to the monitoring controller in order to identify a failure of the actuator and consequently apply a degraded operating mode.
