通过对桥式起重机大车运行运动路径的分析和位移检测装置对大车走偏的实时采样监控，建立了基于位置式PID控制的大车防走偏数学模型及控制模型，并以大车位移调整量为分离阈，将此控制策略采用Matlab仿真进行验证，确保在大车运行过程中，大车轮走偏的情况下，控制系统进行自整定，大车电机进行自调整，实现桥式起重机稳定安全的运行。
通過對橋式起重機大車運行運動路徑的分析和位移檢測裝置對大車走偏的實時採樣鑑控，建立瞭基于位置式PID控製的大車防走偏數學模型及控製模型，併以大車位移調整量為分離閾，將此控製策略採用Matlab倣真進行驗證，確保在大車運行過程中，大車輪走偏的情況下，控製繫統進行自整定，大車電機進行自調整，實現橋式起重機穩定安全的運行。

Through research and analysis of the motion path of the bridge crane,real-time sampling monitoring is car-ried out for crane deviation with displacement detecting device.The crane anti-deviation mathematic model and control mod-el are developed based on positional PID control.With the crane displacement adjustment as the separating threshold,the control policy is verified by MATLAB simulation,to guarantee self-tuning of the control system and self-adjustment of crane motor in case of deviation of crane wheel during crane running,in order to realize stable and safe operation of the bridge crane.
