Abstract

Abstract:

In view of the problem that the measurement equation and transfer function of the traditional closed-loop decoding algorithm are easy to cause steady-state errors during acceleration,an improved closed-loop decoding algorithm is proposed in this study.Before the closed-loop solution, the least square method is used to fit the output signal parameters of the rotating transformer to obtain a more accurate signal of the rotating transformer. The calibration device is designed to avoid the influence of parameter fluctuation and nonlinear factors on the system performance and enhance the stability of the system.The steady-state error, angular position error and angular velocity error of the decoding algorithm are analyzed by simulation experiment. The results show that the improved closed-loop decoding algorithm is more stable and the steady-state error is smaller.Angular position error fluctuation from (-10, 0) to (-4.0,3.5), the angular velocity error fluctuation from (-0.50,-0.25) to (-0.15,0.10).

Key words: rotating transformer, position signal, transfer function, angular position, closed loop decoding, algorithm, signal analysis, steady-state error
