Research on tractor tillage depth control based on AMESim-Matlab joint simulation
In the research of tractor electric and hydraulic depth control system,the joint control method and control strategy of force-position synthesis and slip rate are proposed.The slip rate monitoring control is added to the force-position comprehensive control to adjust the depth of tillage within the allowable range of the optimal slip rate range.The hydraulic physical model of the electronically controlled hydraulic hitch system is built through AMESim software,and the simulation model is established through joint simulation with Matlab/Simulink software.The slip rate fuzzy controller and the force level integrated fuzzy PID controller are designed.The multi parameter control effect based on the slip rate logic threshold is studied through experiments.The test results show that the system has a good response effect when the slip rate logic threshold is exceeded,it has a better following effect on the change of slip rate,which provides a theoretical basis for the multi parameter control of the tractor tillage depth control system.
