ABSTRACT
The paper described the production of circuit AC motor control, explore a shortcuts control of AC motor. Elaborate how to make vector control, and have finished the AC motor vector control system hardware architecture. I have grasped the development overview of AC system and its working space. I have also know that the research status at home and abroad. According to the large reality of Chinas energy consumption, promoting the traditional DC motor speed control system.
This design used Protel 99 SE to make PCB and schematic, make use of MULITSIM to simulate the Inverter circuit, protection circuit, voltage acquisition, current acquisition. Make full use of the resources at hand to the AC motor control theory and the stage of implementation.
As can be seen from the simulation and experimental waveforms, the system allows a large range of smooth speed. It has strong control accuracy and good dynamic performance. The experimental results verify the effectiveness and feasibility of the system design, and laid a solid foundation for further development and utilization of new laboratory equipment.
