Abstract

The invention belongs to the technical field of industrial robot driving and especially relates to an industrial robot intelligent driving system. The output of a position giving module is connected to the giving end of a position comparison PID adjustment module. The output of the position comparison adjustment PID module is connected to the input end of a position limiting module. The output of the position limiting module is connected to the limiting end of a speed comparison PID adjustment module. The output of the speed comparison PID adjustment module is connected to the giving end of a current comparison PID adjustment module. The output of the current comparison PID adjustment module is connected to a power amplification module. The output of the power amplification module is connected to the motor execution module. According to the system, the problems of a large starting torque inertia ratio and poor following characteristic in the prior art are solved, and the system has the advantages of a good following characteristic, a high starting torque, high safety, and a wide range of application.

Description

technical field [0001] The invention belongs to the technical field of industrial robot driving, and in particular relates to an intelligent driving system of an industrial robot. Background technique [0002] For motors driven by joints of industrial robots, maximum power-to-mass ratio and torque-to-inertia ratio, high starting torque, low inertia, and a wide and smooth speed range are required. Especially for robot end effectors (claws), motors with the smallest volume and mass should be used, especially when fast response is required, the servo motor must have high reliability and stability, and have a large short-term overload Ability, which is a prerequisite for the application of servo motors in industrial robots, the prior art has the problems of large starting torque-to-inertia ratio and poor following characteristics. Contents of the invention [0003] The present invention provides an intelligent driving system for an industrial robot to solve the problems in th...
