Co-simulation Analysis of Synchronous Control of Monorail Crane Hoist Motor
To improve the self-adaptability of the monorail crane lifting hydraulic system in the face of biased load start,sudden load change,and system speed regulation,and to better meet the demand for intelligent remote control of monorail crane,a BP-PID control based monorail crane hydraulic lifting synchronization control system was proposed.Firstly,the principle of the hydraulic system was analyzed,and the principle of speed control and synchronization control strategy was analyzed.Secondly,the principle of the BP neural network was analyzed,and the BP-PID controller was designed.Finally,AMESim and MATLAB/Simulink were used to build the hydraulic system model and synchronous controller model,and the system was compared with PID control to analyze the off-load starting characteristics,anti-load abrupt change characteristics,and system speed control characteristics.The simulation results showed that the BP-PID control can effectively reduce the overshoot and maximum synchronization error of the hoist motor and reduce the response time of the system when the load is off.When the load changes abruptly,the system adopts BP-PID control to effectively reduce the maximum synchronization error and the system response time,so that the system has better robustness.When speed regulation,the system adopts BP-PID control to effectively reduce the crane motor overshoot and reduce the system response time no matter the target speed increases or decreases.
