Magnetic Levitation System Control Based on Improved LADRC

In response to the problem of poor anti-interference and stability caused by the complex structure of the magnetic levitation ball system, an improved sparrow search algorithm (ISSA) combined with linear active disturbance rejection control (LADRC) is adopted to solve the above problems. Firstly, a mathematical model of magnetic levitation ball was established based on the research object of magnetic levitation ball; Secondly, an improved sparrow search algorithm is used to adjust the parameters of the linear active disturbance rejection controller (LADRC) to achieve stable control of the magnetic levitation ball; Finally, PID, LADRC, and ISSA-LADRC were introduced for simulation analysis and experimental verification. The final results indicate that ISSA-LADRC has strong stability and anti-interference ability.
