Abstract
With the continuous improvement of industrial automation, electric motors, as crucial power equipment, have been widely applied in various fields. However, traditional motor control systems suffer from poor speed regulation performance and high energy consumption. This study investigates a PLC-based speed regulation and energy-saving control method for motors, aiming to enhance speed regulation performance and achieve energy efficiency. By analyzing the operating principles and speed regulation requirements of motors, a control system centered on a PLC is constructed. Leveraging the robust logical operation capabilities of the PLC, precise speed control of the motor is achieved. Frequency conversion speed regulation technology is employed to alter the power supply frequency of the motor, enabling stepless speed regulation. Additionally, a fuzzy control algorithm is introduced to optimize the speed regulation process, ensuring stable operation at optimal speeds under varying loads. Experimental results demonstrate that this method enables smooth motor startup, rapid response, and high speed regulation accuracy. Compared to traditional control methods, it achieves significant energy savings with an average energy efficiency improvement of over 30%. Innovatively combining PLCs with frequency conversion speed regulation and fuzzy control for motor speed and energy-saving control, this research provides a novel approach and methodology for motor control systems, contributing significantly to the advancement of motor control technology and energy conservation efforts.
