    摘要: Interruption in supervisory position control signals can cause problems with respect to actuators which upon loss of such control signals for the actuator will generally slew to a fixed idle position. In such circumstances a machine such as a gas turbine engine in which an actuator is associated will not sustain performance even though there is continued local power supply to the actuator. By utilising a local controller which stores actuator response profiles for certain machine status stages through perturbation or marginal activation of the actuator an appropriate actuator response profile can be chosen and therefore sustaining control signals presented to the actuator to maintain machine operation.

    摘要: The present invention is related to a method of controlling an actuator having a calibration process. The calibration process has a partial calibration routine and a calibration routine. The control system is capable of receiving one or more input signals and determining whether a partial calibration or calibration should occur. The first step in the process involves starting the control method where the actuator receives input signals or generates its own data within the actuator. A determination whether a partial calibration routine or a calibration routine will take place is based upon the value of the input signals received. A partial calibration routine will be performed if the input signals do not favor a calibration.

    摘要: A hydraulic system includes a solenoid operated means (24) generating a first hydraulic fluid pressure which is connected to a pressure modifier valve means (22) for generating a second hydraulic fluid pressure such that the second hydraulic fluid pressure is variable in response to said first hydraulic pressure. A pressure regulator valve means (20) generates a line pressure variable in response to said second hydraulic fluid pressure. Thus, the variation characteristic of the line pressure may be easily modified to comply with the output characteristics of different engines without any modifications of the solenoid operated means.
