Research On X-Y Bridge Crane Journey Planning And Drive Control

X-Y bridge crane equipment is widely used in large enterprises such as industrial and mining production and logistics transportation in China due to its advantages of large lifting weight,convenient and fast handling.Traditional X-Y bridge crane have problems such as low positioning accuracy,low efficiency,and unstable operation,which seriously restrict production efficiency.This article conducts research on X-Y travel planning and driving control,proposes a compact format modelless adaptive controller based on PSO algorithm(PSO-CFDL-MFAC),and achieves high-precision control of X-Y driving motor;On this basis,an X-Y intelligent travel planning system for driving was designed based on PLC,achieving travel planning.It plays an important role in ensuring stable driving and reducing operating costs.Firstly,based on practical application scenarios,the structure and transmission system of the X-Y driving system were selected,including key components such as asynchronous motors,precision tracks,and main frames.The power of the driving system was estimated,and the calculation of wheel technical parameters and reduction ratio was completed.Secondly,mathematical modeling and Matlab/Simulink simulation were conducted on the wound three-phase rotor asynchronous motor,which is the driving device of the X-Y bridge crane in this article.To ensure the effectiveness of modeling and simulation,the influence of iron loss on motor modeling was fully considered during the modeling process.Thirdly,considering the limitation of the control performance of the traditional PID controller,a PSO-CFDL-MFAC controller based on the PSO algorithm is proposed,and three closed-loop control simulation experiments are designed for the position,speed,and current.The comparison experiment results show that compared with the traditional PID controller,the speed Rate of convergence of the PSO algorithm based compact format model free adaptive controller is increased by 60%,and the Step response is not overshoot,Better robustness;The oscillation amplitude of the motor torque is smaller,and the amplitude decreases by12.5% near the 35.7Nm position;The steady-state error of position control is reduced by 1%,resulting in better control performance.Finally,based on the Siemens PLC system,the X-Y intelligent travel planning system design was completed,including hardware configuration,software program design,configuration screen production,etc.,and the intelligent travel planning of the vehicle was achieved following the principle of energy optimization.
