Abstract :
In order to overcome control overshoot of the electric-control hydraulic system, steering wheel and environment factors and external disturbances on nonlinear steering control, realizing rapid and accurate response to wheel movement, a double closed-loops control system was designed using the Dongfanghong X-840 tractor as a platform in this paper. The angle sensor KMA199 was used to measure angle, and ADIS16300 gyroscopes to measure angular velocity. Both results from the sensors real-time feedback to the operator control unit, forming a double closed-loops control system. The results show that: the double closed-loops control system solved the control overshoot well, and the maximum error is 0.6 °, average error 0.21 °, average delay 0.2s.
