High-precision fault-tolerant self-driving seat system

Abstract

The invention relates to a high-precision fault-tolerant self-driving seat ring system, including a fault-tolerant motor system, a position sensor, a slip ring, and a load; the fault-tolerant motor system is composed of a fault-tolerant motor, a fault-tolerant drive topology and a fault-tolerant controller. When the topology fails separately or at the same time, by adopting the fault-tolerant control technology, the system can ensure that the system has a first-degree fault tolerance and a first-degree fault operation capability, and mainly realizes high power density and high reliability operation; the integrated design of the motor and the raceway realizes The seat ring is self-driven, and the transmission gap of the traditional seat ring is eliminated, realizing high-precision and high-efficiency operation. Compared with the "drive motor + gear reducer" scheme, it improves the precision and transmission efficiency of the seat ring system, eliminates the transmission gap, vibration, noise, wear, etc., and also greatly reduces the manufacturing process and assembly difficulty, and improves Follow-up maintenance.

Description

[0001] Technical field [0002] The technical invention relates to the technical field of servo control, in particular to a high-precision fault-tolerant self-driving seat system. Background technique [0003] Nowadays, the mechanical structure of seat rings of armored vehicles, tanks and other turrets and weapon stations at home and abroad often adopts the cascade drive scheme of "drive motor + gear reducer". Regardless of the electro-hydraulic or all-electric gun control system, in order to improve the response speed of the turret, the power components usually use high-speed motors, which requires the addition of multi-stage reducers to amplify the output torque to bring the load to motion. As we all know, the use of multi-stage gear reduction will reduce the transmission accuracy of the seat ring, increase vibration and noise, etc., and there are inevitably transmission gaps, gear elastic deformation and wear problems in the gear transmission device, and the adoption of thi...

Problems solved by technology

As we all know, the use of multi-stage gear reduction will reduce the transmission accuracy of the seat ring, increase vibration and noise, etc., and there are inevitably transmission gaps, gear elastic deformation and wear problems in the gear transmission device, and the adoption of this scheme will increase the system manufacturing process. Difficulty and assembly difficulty will further increase the subsequent use and maintenance cost of the seat ring

At the same time, the nonlinear link in the above-mentioned transmission chain will have a significant impact on the stability, low-speed performance and stable accuracy of the gun control system, which restricts the performance of the fire control system of the turret and weapon station, thereby reducing the battlefield survival rate
