摘要
惯性稳定平台在运行过程中会受到内部和外部因素的影响,这些因素的变化引起被控对象的参数变化,进而降低系统的控制精度。本文提出在惯性稳定平台的速度回路内增加高增益的加速度闭环校正,可以很好地补偿被控对象参数变化的不利影响。并且由于加速度计为惯性敏感元件,加速度内回路还具有扰动抑制能力,惯性稳定平台的主动抑制能力等于加速度回路和速度回路抑制能力之和。实验证明,加速度反馈闭环增强了惯性稳定平台的主动抑制能力。
The performance of the inertial stabilized platform will be affected heavily by inner or outer factors, which will change the transfer characteristic of the inertial stabilized platform and result in the degradation of the precision of the system. Therefore, the high-gain acceleration feedback will be inserted in the velocity feedback loop to compensate the change of these factors. And the acceleration feedback loop can stabilize the platform because that the accelerometers are inertial sensors, the active disturbance suppression of the platform is the product of the error attenuation of the acceleration loop and the velocity loop. Extensive experimental results show that the acceleration feedback can enhance the active disturbance suppression of the platform.
