Research on Multi motor Synchronous Control System Based on Second Order LADRC

The synchronization error of multi motor synchronous control system in steady state is large when the load changes, and the tracking performance and anti interference performance of the system are poor. To solve the above problems, a second order linear active disturbance rejection controller based on an improved speed compensator was proposed.Under the environment of MATLAB/Simulink, three motor synchronous control simulation experiment models were built and simulated. The improved deviation coupling control structure and the traditional deviation coupling control structure were compared and analyzed. The research results show that the improved deviation coupling control structure has the characteristics of high precision, good anti interference performance, and fast convergence speed.
