摘要

摘要:
为了研究宽频带的隔振问题，以使系统具有较好的隔振效果，提出将电磁悬浮隔振与机械隔振相结合的复合隔振系统. 首先，对所设计的隔振系统进行动力学建模，分析线性化后的模型控制特性；其次，针对系统振动控制问题，提出基于自抗扰技术的控制器设计方案，并通过仿真实现了复合隔振系统的自抗扰控制；最后，在复合隔振平台上验证了该控制方案的可行性. 研究结果表明：在0~10 Hz频段控制系统能实现较好的低频跟随效果，在10~100 Hz频段幅值衰减逐渐增大，在100~300 Hz频段的隔振效果超过−14.9 dB. 本文所提出的控制方案为复合隔振系统控制提供了一种新思路.

Abstract:
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.
