Abstract

The invention relates to an automated guided vehicle control method and system. The method comprises the steps of obtaining the current speed difference of a to-be-controlled automatic guided vehicle;obtaining a magnetic bias value identification model; determining a magnetic bias value corresponding to the current speed difference according to the current speed difference by utilizing the magnetic bias value identification model; adopting a PID controller to determine the speed difference of the automatic guided vehicle to be controlled at the next moment according to the magnetic bias valueso as to complete control over the automatic guided vehicle to be controlled, wherein the PID controller is a PID controller after parameter searching based on a hybrid particle swarm optimization algorithm. According to the automatic guided vehicle control method and system provided by the invention, the magnetic bias value is determined by adopting the magnetic bias value identification model,so that the system modeling error can be reduced, and the model accuracy is improved. The PID controller subjected to parameter searching through the hybrid particle swarm optimization algorithm is adopted for control, so that the control efficiency, the control precision and the robustness are improved.

Description

technical field [0001] The invention relates to the field of automatic guided vehicle control, in particular to an automatic guided vehicle control method and system. Background technique [0002] With the development of modern logistics production and the continuous improvement of the degree of automation, the production and logistics methods of traditional manufacturing have undergone profound changes, and automated guided vehicles (AGVs, Automated Guided Vehicles) have become more and more widely used in the field of production logistics. The introduction of AGV has greatly improved product quality and production efficiency. At the same time, higher requirements are put forward for the automation, flexibility and punctuality of material handling operations in the production workshop. AGV technology is an important research field developed under this background. [0003] AGV is widely used in machinery, automobile, medical, cigarette and other industries. As the complex...
