Abstract

The invention provides a path tracking control method of a handling robot based on a neural network, which can improve the real-time performance of nonlinear model predictive control. The method includes: using nonlinear model predictive control to generate a training sample set, wherein the training sample includes: state variables and control variables of the handling robot; constructing a neural network model; using the obtained training sample set to train the constructed neural network model , to obtain a trained neural network model; wherein, in the path tracking control process, the trained neural network model outputs control variables, so that the handling robot performs path tracking according to the control variables output by the neural network model. The invention relates to the field of autonomous driving control of mobile robots.

Description

Technical field [0001] The present invention relates to the field of mobile robots, in particular, refer to a path tracking control method of a neural network based handling robot. Background technique [0002] The unmanned navigation of the handling robot is to collect the vehicle real-time position and position postage information by installed environmental acquisition equipment such as global positioning system (Global Positioning System, GPS), Ultra Wide Band, UWB, and then The acquired information is input to the path planning module, which further plans an optimal path, and transmits the path tracking control module, and calculates the optimal control amount and issues to the actuator to complete the automatic driving. The handling robot can track the operation along a planned feasible path from its location, quickly reaching the designated location, which is the path tracking problem of the handling robot. Path Tracking Control is the most basic and most core function in t...
