abstract:
In order to solve the problem of straight-line running deviation of electric bulldozer, the simulation model of tracked electric bulldozer was established, and the influence factors of straight-line running stability were analyzed by using the model. According to the analysis results, the difference of response characteristics between two motors, the difference of moving devices on both sides or the difference of load on both sides can cause the deviation of bulldozer, and the difference is positively correlated with deviation. The control strategy based on fuzzy PID was designed, and the yaw angular velocity of bulldozer was chosen as the feedback parameter of straight-line stability control. A comparative simulation analysis of two cases with or without straight-line running stability control was carried out, and the simulation results showed that the yaw angular velocity of bulldozer can be controlled at 0 rad/s, which verifies the feasibility of the strategy.
