The invention discloses an estimation method and estimator for sideslip angle of straight-line navigation of agricultural machinery, which collect and analyze front wheel steering angle information, forward speed information of agricultural machinery, antenna positioning information and current attitude information. The estimation of sideslip angle is realized based on state observation theory. The first estimator, the second estimator and the third estimator are used to estimate the heading deviation of the vehicle body, position deviation and sideslip angle information. In the analysis process, integration is used instead of differentiation, which avoids the error of amplification by differential operation.
