In order to study broadband vibration isolation and make a system have better vibration isolation performance, a compound vibration isolation system combining electromagnetic suspension isolation and mechanical spring isolation is proposed. First, a dynamic model of the designed vibration isolation system is established, and the control characteristics of the linearized model are analyzed. Aiming at the problem of system vibration control, a controller design scheme based on active disturbance rejection technology is then presented, and the active disturbance rejection control of system is realized by simulation. Finally, the feasibility of the control scheme is verified on a compound vibration isolation platform. The experimental results show that the control system in 0−10 Hz frequency band can achieve good performance of low-frequency tracking, the amplitude attenuation increases gradually in 10−100 Hz, and the vibration isolation effect in 100−300 Hz frequency band exceeds −14.9 dB. The control scheme proposed in this paper provides a new idea for the control of the compound vibration isolation system.
