Abstract

The invention relates to the technical field of robot control and particularly relates to a smooth data processing method and system. The method includes acquiring and storing the running parameters of a motor; performing smooth data processing of the running parameters of the motor to obtain a new sampling value; and transmitting the new sampling value to the motor after three rounds of calculation to realize the closed loop control of the motor. According to the method, the current, position, and speed information acquired by the motor is transmitted to a control module to carry out the closed loop control after being subjected to the data smoothing processing, the disturbance signal caused by the hardware interference can be effectively reduced, the useless burrs can be filtered, so that the sampling result is more close to the reality, the optimal control of the motor is achieved, the motor running performance is improved, and the running smoothness is increased. Therefore, the robot can run more stable.

Description

technical field [0001] The invention relates to the technical field of robot control, in particular to a smoothing data processing method and system. Background technique [0002] Data smoothing is very important for digital systems with interference, it is the premise of data statistics and analysis, and it is the most cumbersome link in information systems. Existing hardware is smooth. Because resistors, capacitors, inductors and other components are used to build circuits, issues such as impedance matching need to be considered, and the precision is limited, and the components used are sensitive to voltage, temperature, and noise. The hardware components are coupled with each other to generate interference signals, which is not good for the original signal. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a smoothing data processing method and system. A smoothing data processing method includes: collecting ...
