Embodiment Construction

[0027] Such as figure 1 As shown, the present invention includes a redundant drive controller part 1 , a steering gear part 2 and a steering surface part 3 . The redundant drive controller part 1 receives the given signal of the rudder surface position, and is controlled by the control method to drive the double-redundant brushless DC motor 4 in the steering gear to work, so that the turning angle of the rudder surface follows the given signal of the rudder surface position. In the present invention, the control power supply, drive power supply, motor winding, motor Hall sensor, position sensor, and power drive unit are designed for backup.

[0028] Wherein, the redundant drive controller part 1 includes a control surface position feedback conditioning unit 5, a control surface position given receiving unit 6, a DSP unit 7, a CPLD unit 11, an isolation circuit unit 12, a power drive unit 13, a current acquisition unit 8, Overcurrent protection auxiliary unit 9 and power syste...

Abstract

The invention discloses a dual-redundancy actuator system and a control method. A redundant drive controller receives a control plane position given signal and drives a dual-redundancy brushless direct-current motor to work, and a turning angle of a control plane follows the control plane position given signal. Redundant technology is used for warm backup of mechanisms, which are easy to damage, in an actuator drive device, the position of the control plane can normally follow the given signal under the normal condition, when a redundancy of the drive device fails, a fault point can be detected in real time and is isolated, a control plane tracking function is finished in a single channel, and accordingly the reliability of the actuator system is improved.

Description

technical field [0001] The invention relates to a dual-redundancy steering gear system and a control method. Background technique [0002] The rudder control system is an important actuator of the flight system. The rudder controller can control the deflection of the rudder surface, thereby controlling the change of the flight attitude to achieve yaw and flip. [0003] At present, the steering gear redundancy control system has developed rapidly and achieved remarkable results. The patent "Dual Redundancy Steering Gear Controller" with the publication number CN101799689A adopts a dual redundancy design, but the controller only backs up the power drive circuit with redundancy, and does not perform fault diagnosis and isolation. The overall performance of the steering gear system. The article "Dual Redundancy Steering Gear Control System Design" published in "Micro-motor" introduced the dual-redundancy steering gear control system based on DSP and CPLD, but the design of the...
