Abstract

The invention discloses an optimal trajectory planning method and device for control compensation and a storage device. The method comprises the steps: generating an optimal motion trajectory according to information inputted by an upper computer, and generating control compensation information corresponding to the optimal trajectory while considering an error caused by receiving a discrete control signal by a controller. The method has the advantages that the real-time performance of robot control and the trajectory tracking precision are improved in the process, meanwhile, a trajectory space conversion tool is added in the method, the inverse kinematics solving efficiency of a robot which does not meet the Pieper criterion is improved, and the real-time performance of trajectory planning is further improved.

Description

technical field [0001] The invention relates to the field of robot trajectory planning, in particular to an optimal trajectory planning method, device and storage device for control compensation. Background technique [0002] Trajectory planning is to design the speed and acceleration of each joint according to the actual requirements of the operation, so that the controlled system can reach a specific target state within a specified time. Trajectory planning can be subdivided into basic trajectory planning and optimal trajectory planning, in which basic trajectory planning only considers the kinematics characteristics of the controlled system for the reproduction of motion; optimal trajectory planning is further considered on the basis of basic trajectory planning Dynamic characteristics, transforming the trajectory planning problem into a constrained nonlinear programming problem for solving. [0003] Basic trajectory planning can be divided into Cartesian space planning ...
