摘要
采用三状态反馈控制和三状态顺馈控制可提高地震模拟振动台(振动台)系统加速度响应频宽,增强系统稳定性应用极点配置原理设计了振动台的水平向和垂直向激振系统的三状态控制器.由于三向六自由度振动台水平向和垂直向激振系统的参数不同,因此三状态控制器的结构和参数也不同.对水平向激振系统,由于其液压固有频率较低,采用二阶补偿改善系统的频率特性;对垂直向激振系统,由于其液压固有频率与要求的系统频宽相近,采用一阶补偿改善系统的频率特性.
The frequency band and stability of Seismic Simulating Shaking Table (shaking table) can be improved by three state controller-three state feedback and three state feedforward controller. Pole-assignment theory is em-ployed to design the three state cotroller of the Shaking Table. For there is a parameter difference betWeen the hori-zontal control systems and the vertical control systems, the strUcture and the Parameter of the three state cotrollerfor them is also different. the natUre freqUency of the horizontal control systemS is far less than the shaking table'sfreqUency band reqUired, the 2 order compensation feasible is feaSible, and that of the horizontal control systems iseqUal approximately to the shaking table'S frequency band required, the l older inertia compensation factor is feasi-ble.
