The non-model robot multi-peg-in-hole assembly control method capable of using the environment forecasting for the optimization uses a universal operating value function for forecasting environmental related knowledge, designs a fuzzy logic system according to human assembly experience, uses learned knowledge forecast as input, and outputs parameters used for optimizing a non-model control algorithm, and when the number of iterations of a deep reinforcement learning network reaches the upper limit and assembly meets requirements, the deep reinforcement learning network after completing training is output and used for outputting assembly action during the multi-peg-in-hole assembly process. The non-model robot multi-peg-in-hole assembly control method capable of using the environment forecasting for the optimization can achieve optimization for the existing non-model robot control algorithm, and shortens time needed in multi-peg-in-hole assembly of a robot.

Description

technical field [0001] The invention relates to a non-model robot multi-axis hole assembly control method optimized by environment prediction, which belongs to the technical field of robot assembly. Background technique [0002] As robots are widely used in industry, robot automation assembly technology has huge market application prospects. At present, deep reinforcement learning networks have been widely used to solve the application scenarios of complex control of actual robots. Based on deep reinforcement learning networks, robots There is no need to model and analyze the contact state in the assembly process, but to learn the assembly skills directly from the environment by trying like a human.
