"高效稳定的基于PLC的直流电机调速系统设计"

Based on the document "Design of DC Motor Speed Control System Based on PLC", this graduation project from the School of Automation and Electronic Information Engineering of **** College focuses on the design and implementation of a direct current motor speed control system using a PLC. The project utilizes the FX2N-16MT basic unit and FX2N-4AD, FX2N-2DA analog input/output expansion modules from Japanese company Mitsubishi. Through the design of a double closed-loop DC PWM speed control system, the project aims to achieve fast speed, high precision, easy parameter adjustment, and high operational reliability. By simulating and testing the output signals based on the given hardware configuration and ladder diagram, the project has successfully verified that all the requirements of the speed control system have been met. In summary, the project successfully demonstrates the application of PLC technology in the design of a direct current motor speed control system, providing a reliable and efficient solution for industrial automation. The use of Mitsubishi's FX2N series modules ensures the system's stability and accuracy, while the double closed-loop design enhances the speed control performance. The project's success in meeting all the specified requirements highlights the effectiveness of PLC-based systems in practical engineering applications.
