摘要
本文根据地震模拟振动台油柱的共振频率较高这一特点,提出了基于速度正反馈的三参量控制技术,并对振动台模拟控制系统进行了改造,并将改造的系统传递函数进行数学推导,确定了能够保证系统稳定的开环增益与阻尼比的取值范围。最终对改造后的系统进行仿真,得出相关结论。
In this paper, according to the resonance frequency with the oil column of simulated earthquake vibration table is higher, it comes up with the three parameter control technology based on speed positive feedback. And the vibration table simulation control system was reformed .Then, this paper will reform the system transfer function of the mathematic model, and it can ensure values of the open-loop gain and the damping ratio. Ultimately for the system after reconstruction has simulated and reaches the relevant conclusions.
