针对当前叉车转向系统工作过程中存在的零点不对应问题，开发一种无差转向系统，以STC单片机为内核，通过PID算法控制电磁阀进行油液补偿，消除转向偏差，实现了机、电、液一体化，使叉车转向过程中方向盘零位与车轮零位精确对应，以利驾驶员操作的便利与安全。

In order to eliminate the zero adjustment error exiting in ordinary forklift steering system, a new type of non-error steering system is developed on the basis of MCU. By controlling electromagnetic valve through PID algo-rithm to accomplish hydraulic oil compensation, the steady relationship between the steering wheel angle and fork-lift wheel angle is finally ensured. Besides, experimental tests prove that the non-error steering system could im-prove the forklift’s steering performance effectively, as well as steering precision.
