Technical Analysis of Servo Control of Permanent Magnet Synchronous Motor
Since the beginning of the new century, various manufacturing industries have achieved breakthrough development. With the update of the level of modern information technology, the industrial manufacturing industry and computer microelectronics have been organically integrated, which has enabled modern industry to achieve huge economic benefits of low investment and high yield. As the central link of mechanical operation, the motor has the most direct impact on mechanical properties. As a relatively high-end service motor in modern machinery, permanent magnet synchronous motor combines with servo control technology to realize the fine control of the internal operation of the motor, which greatly promotes the performance of the motor and becomes the modern advanced manufacturing industry in various countries. The core technology.
Introduction to the servo system
1. The basic structure and working principle of the servo system
The servo system is actually a feedback control system that implements fine control of the mechanical working process, but it is mostly used to control the motion vector of the machine, such as the displacement point, displacement speed and acceleration change process. The technology uses digital AC sine wave control and optimal PID algorithm to complete the PWM control process, and performs data processing according to predetermined control requirements, so as to accurately track and monitor the mechanical displacement process. As a member of the feedback control system, its basic composition still meets the requirements and characteristics of the feedback control system.
The servo control system itself does not have diversity, but its main application is in the control link of mechatronics, and thus has a variety of characteristics.
2. Current status of servo system application
The development of modern AC servo system is fast, and it has undergone a perfect transition from data simulation to full digital. The digital control loop has been widely used in servo systems such as commutation, current and position control. High-performance DSPs and FPGAs, as well as servo-specific engines introduced by IR, are also frequently appearing on the international market. Therefore, although the servo system is a high-end system equipment of the modern manufacturing industry, the appearance in the market proves a good development trend.
The company focuses on the production of ATM reduction motor and auto door motor.
