| 摘 要： | 惯导测试设备(转台)的转速性能对惯性元器件和导航系统的性能测试有着重要影响,转台控制系统中存在的各种周期性扰动会造成转速的周期性波动,严重影响转台速率性能的提高.本文分析了该类设备转速周期性波动产生的机理,并针对周期性扰动幅度难以确定的特征,提出了一种基于非线性自适应控制理论的抑制方法和系统实现方案,该方法能有效抑制因周期性扰动而产生的周期性速率波动,提高转台的速率性能.转台实验表明,该方法对设备中存在的周期性转速波动具有明显的抑制效果.

| Abstract: | The rate performance of inertial guidance test equipment (IGTE) affects the performance testing of inertia devices and navigation systems. Periodic rate ripples caused by periodic disturbances have a great effect on the rate performance of rotation test tables. The mechanism caused by the rate ripple in IGTE is analyzed. Based on the nonlinear self-adaptive control system approach, a control system scheme is proposed to eliminate the period disturbances for its uncertainty. Experimental results show that the periodic rate ripple can efficiently be controlled. |
