Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing.

[0020] Such as figure 1 , figure 2 As shown, the present invention discloses a DC motor intelligent control device, which is composed of two parts, one is an intelligent controller, which is used to intelligently set PID parameters and transmit variables to the PID controller; the other is a PID controller, which is used to Apply the adjusted PID parameters to the control object. By intelligently setting PID parameters for the control object, the separately excited DC motor can quickly and accurately respond to speed regulation requirements without speed overshoot.

[0021] The intelligent controller performs A / D conversion on the signal and the given signal through its own processor; with the MCU as the core, it stores the characteristic curves and algorithms of different motors, and can continuously correct the curve parameters according to the feedback value, and then...

Abstract

The invention discloses an intelligent control device of a direct current motor. The intelligent control device of a direct current motor is formed by two parts: an intelligent controller and a PID controller, wherein the intelligent controller is used for intelligently giving PID parameters and transmitting variables to the PID controller; and the PID controller is used for applying the adjustedPID parameters to a control object. By giving PID parameters to the control object, the intelligent control device of a direct current motor enables a separate excitation-type DC motor to respond quickly and accurately to the speed regulation requirement without the phenomenon of speed overshoot. The invention also discloses an intelligent control method of a direct current motor. The intelligentcontrol method is self-adapted to different motor characteristic curves, and enables the DC motor to quickly and accurately respond to the speed regulation requirement without the phenomenon of speedovershoot by intelligently giving 3 parameters: armature voltage armature current and field current.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to an intelligent control device for a direct current motor and a control method capable of intelligently setting parameters of a separately excited direct current motor. Background technique [0002] The existing DC motor control system uses two control loops, the current loop and the speed loop, to adjust the voltage and current during the speed regulation process. [0003] In the process of speed regulation, it is easy to overshoot the speed, the speed regulation time is too long, etc., and the self-regulation ability is average when the stable operation is disturbed. It cannot fully meet the application requirements of high speed regulation precision and fast response. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an intelligent control device and method for DC motors. By adjusting ...
