Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The goal of this design is to develop a fuzzy control system, so that the AGV car can automatically navigate according to the control algorithm within a suitable time. Today's navigation problem is mainly the navigation of curved roads. To improve the efficiency of safe navigation, run times and distances must be minimized. In order to achieve this, the smart car must travel according to the preset trajectory and speed, reducing the amount of deviation. ...

Abstract

The invention relates to a navigation fuzzy control method for an AGV trolley in modern logistics, the navigation fuzzy control method comprises the following steps: a first step, determining input and output variables; a second step, determining variable domains and fuzzy language values; a third step, determining the membership function of each variable; a fourth step, establishing a fuzzy control rule; a fifth step, quantifying input and output quantities; and a sixth step, defuzzifying. Overshoot in a speed inertia adjustment process can be reduced as much as possible due to instantaneousdeviation rate as one variable, the AGV trolley takes less time when driving along a curve, and the working efficiency is improved. A designed fuzzy controller can improve the stability of the systemand reduce errors. Only the rotation speed, as the output quantity, of a drive wheel motor on one side of the trolley is adjusted, the realizability is higher, the fewer regulating system objects are,the smaller system errors are. Therefore, after automatic curve navigation is realized after simulation of the trolley, by adjusting the rotation speed of the driving wheel motor on one side of the trolley, higher profits can be brought to the industrial engineering.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment, and in particular relates to a navigation fuzzy control method of an AGV trolley in modern logistics. Background technique [0002] It is widely used in modern logistics industry and manufacturing industry. Many developed countries in the world attach great importance to the research and development of automatic guided vehicles. It can not only be used as an intelligent means of transportation to liberate labor from heavy and boring handling work and reduce enterprise costs, but also can cooperate with each other to complete assembly and processing in complex and dangerous environments, greatly improving production efficiency. Today, with the advancement of technology, smart logistics vehicles still have certain deficiencies in navigation and path planning. To achieve fast navigation, path planning, and stable operation of the vehicle, many issues still need to be further studied. C...
