Study on Control Algorithm for A Dual Channel Servo System

The paper aims to design a dual channel servo control system in application to positioning platform based on high-precision tracking and pointing requirement and study the algorithm thereof. The paper focuses on introduction to the operating principle of dual channel servo drive system as well as study on dual channel control algorithm, including study of control algorithm for three loops namely current loop, speed loop and position loop for rough channel as well as study of controller parameter setting algorithm for fine channel. Finally, the paper also indicates design method for coordination control strategy for dual channel servo system. Dual channel servo drive system also can also carry out large stroke and high precision movement control, with higher control precision, response velocity and robustness, having been extensively applied to military, aerospace and industry sectors.
