Dc Motor Control System

In electrical time's today, the electric motor in the industry and agriculture production, the people daily life is playing the very vital role. The direct current machine is the most common one kind of electrical machinery, obtains the widespread application in various domains. The research direct current machine's control and the measuring technique, to increase the control precision and the speed of response, the frugal energy and so on have the important meaning.Dissertation is precisely in view of this question, analyzed the monolithic integrated circuit to carry on the velocity measurement to the direct current machine the principle, realized the direct current machine PWM velocity modulation method using the PID algorithm. Take the SPCE061A monolithic integrated circuit as the control core, has realized to the ordinary direct current machine's tachometric survey and the rotational speed adjustment, to further study and the optimization direct current machine control method has provided the foundation. The main research content is as follows:1,establishes electrical machinery's rotation direction, the rotational speed through the SPCE061A monolithic integrated circuit's on 3 pressed keys. The direct current machine rotational speed regulation band 30-60 revolution of/seconds, the stepping value≤2 transfers/the second.2,the real-time measurement electrical machinery's actual rotational speed, and demonstrates on the LED nixietube.3,carries on the PID rotational speed adjustment to the electrical machinery, causes its rotational speed approach in the setting value.This article has certain extendibility, for example the optimization speed regulation algorithm, enhances the rotational speed stability and the speed of response, increases the pronunciation to disseminate news the rotational speed function, or will obtain rotational speed upload to the PC processing and so on. Has provided certain practical significance for the direct current machine control method.
