摘要
高频角振动台控制系统设计的核心问题是如何提高对周期参考输入信号的跟踪精度以及如何提高对周期性干扰信号的抑制能力。由于机械振动和台体结构的限制，系统很难满足角振动台的加速度和带宽的指标。为减少对角加速度陀螺动态指标测试的干扰误差，该文根据重复控制理论提出了高频单轴角振动台的双重复控制器的设计，并推导出该系统的稳定性、鲁棒性和跟踪误差的相关结论，同时给出控制器的设计方法和参数选取的条件。仿真和试验结果表明通过双重复控制器在高频角振动台中的应用，很好地提高了周期信号的跟踪精度，同时提高了系统的鲁棒性。
The main problem for the designed control system of high-frequency angular vibration table is how to promote the tracking precision of the periodic reference input signal and how to the periodic disturbed signal. Due to mechanical vibration and restrict of the construct of table. It is very difficult for the system to meet the index of acceleration and bandwidth of table. To reduce disturbed errors of testing to the dynamic index of angular-accelerometers gyro, the design of dual-repetitive controller is proposed and applied to high-frequency angular-vibration tables, the conclusion about stability,robustness and error convergence is obtained. Simultaneously, it gives designed methods and conditions of choosing parameters. Tracking accuracy and robustness of the system can be improved by applying the dual-repetitive controller to high-frequency angular vibration table.
