Abstract

For the sake of decoupling the six-pole radial active magnetic bearing (AMB) with mutual coupling of two degrees of freedom, nonlinear and unstable disturbance, a hybrid active disturbance rejection control strategy based on improved genetic algorithm (HADRC-IGA) is proposed. Firstly, the configuration, magnetic circuit and suspension force model of the six-pole radial AMB are explained and established. Secondly, the HADRC-IGA is designed which is improved on the linear active disturbance rejection control (LADRC). Thirdly, the simulation is carried out, which shows that the capacity of resisting disturbance and the decoupling efficiency of two degrees of freedom of the HADRC-IGA are better than that of conventional LADRC. Finally, the experimental platform is constructed, and the experiments are conducted, which verify the performance of the proposed decoupled control system.
