Design And Implementation Of The Dc Motor Drive Controller Hardware

Electromotor as the most important device which can convert the electrical energy into mechanial ones ,have been applied in all fields of our country.With the rapid development of computer techinc and micro electronics technic,control strategy of the electromotor have been profoundly changed.Traditional analog control has been replaced by digital control which is based on microcontroller. With modern technic like the microprocessor ,DSP and so on,digital control system have been developed rapidly.This system designed DC electromotor digital control system with TMS320LF2407 DSP controller developed by TI company.It had two closed loop,one was speed loop ,the other was current loop.After analyzing the reliability of the system from considering EMC, this research brought forward completely isolated resolution which made the signal correlative to the DSP completely isolated from the outside. The project also used some new anti-disturbing devices and methods to intensify the reliability of the system and greatly improve the capability of antidisturbing of the whole system.The first capter introduce the background of the design of the DC electromotor controller based on DSP chip. The second capter described the working and control principle of the DC electromotor, brifly introduced the whole desiging frame.The third to fifth capters analysed the design and realization of each part of the circuits.The sixth capter described the debug process of the circuit.
