Abstract

The invention belongs to the field of flight control system design, and particularly relates to a slip monitoring system for a power driving device. Comprising a motor rotating speed sensor, an output shaft position sensor and a servo control module. The motor rotating speed sensor is arranged on an output shaft of the hydraulic motor and is used for acquiring the rotating speed of the hydraulic motor; the output shaft position sensor is arranged on an output shaft of the power driving device and is used for acquiring the rotating angle of the output shaft; and the servo control module is used for judging whether the power driving device slips or not according to signals of the motor rotating speed sensor and the output shaft position sensor. According to the slip monitoring system for the power driving device, the flap power driving device can automatically stop working under the slip condition, abrasion of the power driving device and loss of an energy system due to long-time running after slip caused by overlarge external load are prevented, and the influence on flight safety is further reduced.

Description

technical field [0001] The application belongs to the field of flight control system design, and in particular relates to a slip monitoring system of a power drive device. Background technique [0002] The flap control system is composed of electrical, mechanical or hydraulic devices from the operating device to the actuating mechanism, including the control subsystem and the driving actuation subsystem. The control subsystem mainly completes the collection of system manipulation commands, feedback signal collection, and calculation of control commands. , System operation monitoring and system-level fault monitoring and protection, the drive actuation subsystem mainly undertakes the command signal calculated by the control subsystem to complete the servo drive and actuation. Among them, the power drive device is the core drive component of the system, which is used to receive control instructions, convert hydraulic energy or power supply into mechanical motion, and transmit ...
