Design and Research of Intelligent Irrigation System Based on Motor Control
As the key equipment in farmland irrigation system,the performance of pump motor directly affects the quality and efficiency of farmland irrigation.Aiming at the problems such as single control mode and poor control accuracy of the drive pump,this paper adopted permanent magnet synchronous motor,introduced SVPWM technology for vector control,completed the design of intelligent irrigation system based on motor control,studied and analyzed the structure and working principle of permanent magnet synchronous motor,and established the mathematical model of the motor in three-dimensional coordinates.Vector control technology was used to control the speed and torque of the motor.The overall scheme and hardware circuit design of the intelligent irrigation system were completed.Finally,the performance verifica-tion of the intelligent irrigation system based on motor control was completed through simulation experiment.The results showed that the intelligent irrigation system based on motor control can precisely control the motor speed,torque,torque current and other parameters,and achieve the design purpose.
