AI Technical Summary

Benefits of technology

This technology allows an analog device called this sensor (AD2) to decode its own data accurately even if there are errors during transmission due to external factors such as temperature changes or other environmental issues affecting their performance. It also includes two main components: A processor with advanced processing capabilities and memory storage capacity. These technical features help improve accuracy when analyzing these types of measurements.

Problems solved by technology

Technological Problem: Electronic Equipments like Avionic Computers have become larger due to their increased functionality and complexity. These devices require precise timing and data transmission over an aeronautical communication network that includes multiple components. To prevent this from happening at once, some designs involve duplicated or spare parts mounted within each component's space. However, these solutions may increase costs while reducing efficiency. Therefore, technical problem addressed by the patented solution involves improving the durability and effectiveness of electricity-based flight instruments in environments where they operate correctly.

Embodiment

[0109] like figure 1 As shown, the rotor position angle redundancy control system of the aviation permanent magnet motor is mainly composed of the space vector control FOC algorithm unit, the position angle redundancy control algorithm unit and the AD2S1210 resolver decoding chip. The AD2S1210 resolver decoding chip provides the motor direction signal DIR, the tracking loss signal LOT, the signal deterioration signal DOS, the motor mechanical angular velocity signal Wm, and the motor rotor position angle signal Φ to the position angle redundancy control algorithm unit. The main functions of the position angle redundancy control algorithm unit are as follows:

[0110] a) Convert the motor speed signal n and provide it to the space vector control FOC algorithm unit for closed-loop speed control;

[0111] b) Collect the q-axis voltage vector U'q calculated in the previous sampling period;

[0112] c) Calculate the backup position angle θe according to the information provided by t

Abstract

The invention belongs to the field of aviation permanent magnet synchronous motor control systems, and discloses an AD2S1210-based aviation permanent magnet motor rotor position angle redundancy control system and method. The space vector control FOC algorithm unit is used for generating six paths of PWM (Pulse Width Modulation) waves to drive the three-phase bridge type inversion module to be switched on and switched off by collecting armature current, rotor position angle and rotating speed information of the permanent magnet synchronous motor and adopting a rotating speed and current double-closed-loop control strategy, so that the permanent magnet synchronous motor is controlled to reach a target rotating speed or torque; the AD2S1210 rotary transformer decoding chip is used for collecting rotor position angle information and rotating speed information of a rotary transformer coaxially installed on the permanent magnet synchronous motor. The rotor position angle information and the rotating speed information are decoded and then sent to the position angle redundancy control algorithm unit; and the position angle redundancy control algorithm unit is used for judging the received rotor position angle information, outputting a correct position angle signal to the space vector control FOC algorithm unit, converting the received rotating speed information and outputting the converted rotating speed information to the space vector control FOC algorithm unit.
