under high intensity conditions, only a single peak appears due to c particle thermal radiation, acute fluctuation appeared in peak position, phase advance and without radical light radiation.
superficially it is quite safe to phase advance an accelerometer signal as the error signal has been filtered by the servo and the alrframe transfer function.
和弹体传递函数滤波,所以让加速度计信号经相位超前网路是不会有问题的。
finally, the predictive pi controller designing with linear phase advance filter as predictor is introduced.
