Method and device for improving control precision of robot, robot, storage medium and program product

The invention discloses a method and device for improving the control precision of a robot, the robot, a storage medium and a program product. The method comprises the following steps: acquiring a first state signal of the robot and a second state signal after a preset period; calculating a time delay value according to the first state signal and the second state signal based on a generalized cross-correlation algorithm; obtaining a time delay estimation value based on a recursive least square method in combination with the time delay value; and based on a sliding mode control algorithm, taking the time delay estimation value as an initial estimation control rate to obtain a target control rate of the state signal. According to the technical scheme provided by the invention, the problem that a correct time delay estimation value is difficult to obtain under the condition of a low signal-to-noise ratio by a traditional time delay estimation algorithm is solved, and the influence of communication ...
