Abstract:Aiming at the self-developed programmable dual-axis attitude turntable servo control system, the basic working principle of its motion control system is explained. Aiming at the problems of slow speed, poor accuracy, poor system dynamic performance and stability of traditional turntables, a digital controller based on three closed-loop control of position loop, speed loop and current loop is designed. Completed the software realization of the control algorithm of the control system. Using the LabWindows CVI interactive programming platform to develop the turntable control software, you can change the serial port settings, PID settings, driver settings and other parameters arbitrarily, making the system easy to operate and highly portable. Finally, the position and speed tracking test of the system was carried out. The test results showed that the performance of the system reached the expected, with the characteristics of small overshoot, fast response, high tracking accuracy and good robustness. The system meets the system design requirements and has good application value.
