Research on Motor Speed Control Algorithm Based on Fuzzy LADRC
摘要
The Active Disturbance Rejection Control algorithm of controlling the single motor’s closed-loop speed is put forward to solve two problems in large load disturbances and unstable belt speed for the steel strip three-phase asynchronous motor. The dynamic performance is enhanced by the fuzzy controller dynamically adjusting the bandwidth parameters of the extended state observer. The experimental results verify that the LADRC algorithm optimized with fuzzy control can effectively deal with external load disturbances of the motor and reduce motor speed fluctuations.
