Abstract

The present invention discloses a parameter adjusting system and an adjusting method controlled by direct current motor velocity PID, which belong to the field of direct current motor control. The adjusting system comprises a controller, a power driving unit, a direct current motor and load thereof and velocity detection sensor, wherein the controller consists of a comparator, a proportioner and an integrator. The adjusting method adopts the velocity sensor to detect an actual velocity signal and adopts the comparator to receive the actual velocity signal and a given velocity command signal so as to output an error signal. The proportioner and the integrator receive the error signal respectively to output a proportion control signal and an integral control signal. The power driving unit receives each control signal to output driving current. The direct current motor receives the driving current to drive the load to operate. The system has good static performance and dynamic performance.

Description

technical field [0001] The invention relates to a DC motor speed system and control method, in particular to a DC motor speed PID control parameter adjustment system and adjustment method. Background technique [0002] DC motor speed control must adopt closed-loop control to obtain excellent speed control performance. Only the qualitative understanding of the controlled object can determine what kind of controller to design, and only the quantitative identification of the controlled object parameters can accurately adjust the controller parameters. At present, the known controllers in the prior art, such as the widely used PID (proportional-integral-derivative) controller, do not first determine the parameters of the controlled object, but directly adjust the proportional control parameters of the controller by trial and error or empirical methods , integral control parameters and differential control parameters. Therefore, the adjustment of the controller parameters is re...
