Description

On-board rotor braking system controller with fast plug-in architecture and control method Technical Field The invention belongs to the technical field of flight control, and particularly relates to an onboard rotor braking system controller with a quick plug-in architecture and a control method. Background The helicopter plays an irreplaceable role in the military and civil fields by virtue of the unique vertical lifting, low-altitude hovering and excellent ground-near maneuvering performance. The development trend of the helicopter in the future breaks through the constraint of the working principle of the traditional rotor wing, and evolves to the directions of high speed, long endurance and high maneuverability, which puts forward more stringent requirements on the performance, weight and reliability of each system of the whole helicopter. The rotor braking system is one of core systems for guaranteeing the ground and flight safety of a helicopter, and has the main functions of rapidly and stably braking a main rotor and a tail rotor after an engine is stopped, preventing accidental rotation caused by wind load, accurately controlling the combination and the release of a clutch in the flight state conversion process, ensuring smooth power transmission of a transmission system, protecting the transmission system and reducing the vibration level of the whole helicopter. Therefore, the rotor braking controller is used as a control core of the system, and the performance of the rotor braking controller is directly related to flight safety (avoiding false braking), service life of a transmission system (eliminating combined impact and power hysteresis) and vibration level of the whole machine (ensuring control smoothness). The domestic rotor braking system mainly undergoes the configuration development from mechanical braking, hydraulic braking to electric braking, wherein the electric braking is considered as one of the main braking configuration directions in the future due to the remarkable advantages of quick braking response, easiness in realizing fault diagnosis, light system weight and the like. However, the rotor brake controller currently applied has the following outstanding defects and limitations in meeting the high standard requirement of a new generation helicopter, such as low integration level of ① system architecture, large volume and heavy weight, incapacity of meeting urgent requirements of machine-mounted equipment on compactness and light weight, insufficient ② modularization and maintainability, functional solidification, poor cooperativity, lack of standard modularization interfaces, imperfect fault diagnosis information, inconvenient maintenance, limited expansibility and flexibility of ③ control, closed architecture, difficulty in adjusting the number of control channels according to the requirements of different models (such as controlling a single rotor or simultaneously controlling a main rotor, a tail rotor brake and a clutch), and weak system reconstruction capability. In summary, the existing controllers should control rotor brake, tail rotor brake and clutch simultaneously, and have shortcomings in terms of system architecture, integration level, maintainability, environmental adaptability and expansibility. Disclosure of Invention The invention provides an onboard rotor braking system controller with a quick plug-in architecture and a control method, and solves the problems that the existing rotor braking controller is low in integration level, poor in maintainability and weak in control expansibility, and is difficult to meet the requirements of a new generation of helicopters.
