DC-drive speed system with PWM
ABSTRACT
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. A problem about speed-modulation of DC motor is very important in the field automatic. The requests to the effect after the speed-modulation of the DC motor are different in different fields. Then, different speed-modulation ways are using in different fields.
This paper researches DC-drive speed system with a dual-converter and dual-closed-loop based PWM, discussing a new control method that combines PWM with D C-drive, designs applies in direct current motor's double closed loop current velocity modulation system. DC motor is used very generally because its speed-modulation effect is very good and its speed-modulation is easily to be realized. PWM theory is used most generally among the speed-modulation ways. The text will introduce the H-PWM way mostly. We will try to do modulation to the DC motor with SG3525. The importance of the text is the parts which are composed the system. Another importance is the principles of working about every parts.
