Abstract
The invention discloses a system and a method for controlling the speed PID of a direct current (DC) motor, belonging to the field of DC motor control. The structure comprises a controller, a power drive unit, a controlled object and a speed detection sensor, wherein, the controller comprises a comparator, a proportioner, an integrator and an adder; the controlled object comprises a DC motor and a mechanical load; the control method of the control system comprises the steps as follows: an equivalent damping parameter K and an equivalent inertia parameter A of the controlled object are recognized; furthermore, an proportion control parameter KP and an integral control parameter KI of the controller are adjusted. During the debugging process of the control system, the controller parameters can be adjusted effectively, the blindness of adjusting the PID controller parameter is avoided so that the time and energy are saved, and the best speed control effect can be obtained.
Description
technical field The invention relates to a DC motor speed control system, in particular to a control method for a DC motor speed PID control system, and belongs to the field of DC motor control. Background technique The speed of DC motor must adopt closed-loop control to obtain excellent speed control performance. The closed-loop control system of DC motor speed includes the controller and the controlled object. How to adjust the parameters of the PID (proportional-integral-differential) controller in a targeted manner according to different controlled objects in the DC motor speed control system is a problem to be solved in the prior art. At present, in the known prior art, the proportional control parameters, integral control parameters and differential control parameters of the PID controller are adjusted directly by trial and error method or empirical method, rather than adjusting according to the parameters of the controlled object. The adjustment of the DC motor speed...
