Problems solved by technology

[0003] In anti-skid control, although the traditional PID control algorithm has the advantages of simple algorithm, high precision, and strong reliability, but for some process of system parameter change, PID control cannot effectively carry out online control, and cannot meet the requirements of the system parameter change process. The requirement that the PID parameters should be changed correspondingly at the same time will seriously affect the control effect.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the drawings.

[0015] Such as figure 1 with figure 2 As shown, an anti-skid control method of a mining dump truck is to prevent the vehicle from slipping or idling during driving, starting or accelerating, especially to prevent the vehicle from slipping on an asymmetric road. The specific steps are:

[0016] (1) Detect the front wheel speed separately And rear wheel speed , And compare and analyze the difference between the speed of the front and rear wheels in real time;

[0017] (2) Compare and calculate the difference E between the front and rear wheel speeds and the rate of change C(E) of the difference between the front and rear wheel speeds;

[0018] (3) If the front and rear wheel speed difference E and the rate of change C(E) of the front and rear wheel speed differences are within the specified range, control is performed according to the driver's intention to operate. If it is not within the...

Abstract

The invention discloses an anti-skid control method of a mining dump truck, which belongs to the technical field of engineering machinery. The method comprises the following specific steps of: respectively detecting front wheel rotation speed and rear wheel rotation speed; comparing to obtain a difference E between the front and rear rotation speeds and a change rate C (E) of the difference between the front and rear rotation speeds; if the difference E between the front and rear rotation speeds and the change rate C (E) of the difference between the front and rear rotation speeds fall within a specified range, entering a normal control mode; if the difference E and the change rate C (E) do not fall within the specified range, entering a fuzzy PID controller; analyzing the difference E between the front and rear rotation speeds and the change rate C (E) of the difference; and then determining a PID (Proportion Integration Differentiation) parameters according to the fuzzy control rule; transmitting the adjusting result of the fuzzy PID controller to an inversion controller; and changing the conducting state of an IGBT (Insulated Gate Bipolar Transistor) by using the inversion controller according to the received data so as to change the rotation speed of the wheel. The anti-skid control method of the mining dump truck, disclosed by the invention, has the advantage that the operation status of the wheel can be detected in real time so as to effectively improve the stability and the safety of the wheel in operation.

Description

Technical field [0001] The invention relates to a control method, in particular to an anti-skid control method of a mining dump truck, belonging to the technical field of engineering machinery. Background technique [0002] The anti-skid control system of the vehicle is to prevent the vehicle from slipping or idling during driving, starting or accelerating, especially to prevent the vehicle from slipping on asymmetric roads, thereby effectively improving the vehicle's maneuverability and stability Sex. [0003] In anti-skid control, although the traditional PID control algorithm has the advantages of simple algorithm, high accuracy, and strong reliability, PID control cannot effectively perform online control in the process of some system parameter changes, and cannot meet the requirements of system parameter changes. When the PID parameters are changed accordingly, the control effect is seriously affected. Since the 1990s, some scholars have begun to study and analyze fuzzy cont...
