Description

technical field [0001] The invention belongs to the technical field of servo motor control, and in particular relates to a dual-core servo drive system and an online modeling method for a servo motor. Background technique [0002] The servo system can accurately track the reference signal process and widely exists in the fields of CNC machine tools, wind power generation, and industrial manipulators. The execution structure of the servo system is a servo motor. The incremental photoelectric shaft encoder detects the angular displacement and angular velocity of the system and feeds it back to the controller. The controller compares and calculates the feedback signal and the given signal to generate a control signal. Realize servo control. [0003] Because the proportional-integral-derivative (PID) controller is simple in design and easy to realize, more than 90% of motor servo controllers in the industry use PID control algorithm. However, this algorithm has a disadvantage,...
