Problems solved by technology

[0003] Servo test bench controllers imported from abroad can achieve high control accuracy, but this type of test bench has high requirements on test pieces and test environment conditions, and is expensive, so it is more suitable for scientific research experiments, while domestic manufacturers and users Most of them use computer plug-in boards to measure and control the servo test bench. This method has low precision and poor control reliability, which seriously restricts the development of my country's test equipment industry.
