Abstract of the text
The text is about a inverted double-circle direct-current system that is controlled by chip microcomputer. It adopts GTR-PWM. It is a new kind of controlling system. For it is a kind of high frequency controlled type device, it is convenient to control its working or not. Besides its simple structure, it also has the high switch frequency , low pulse float in the power circuit and excellent low speed function.
The system is wholly controlled by the chip microcomputer. The system contains two kinds of functions, namely the anti-electricity following control and regulating the control with the PI 。 The two kinds of controlling methods cut over automatically in circulate process. It also contains several self-trouble adjusting.
For the sake of high performance technique index sign and multi-function from examining the trouble, it adopts double- CPU in control system and double-pole type PWM in the power circuit. The system adopts Hall sensor and light to electricity coding device, approaching type A/D.
The text mainly works at the direct-current adjusting system that controlled by chip microcomputer and its self-trouble adjusting. I hope that it can gives somebody some help in his work.
Key words: single chip microcomputer, GTR—PWM direct-current adjusting system, PI adjusting, The versa electromotive force follows adjusting.
