AI Technical Summary
Technical Problem
Continuously rotating radar systems are prone to shocks and oscillations during the stopping process, which may damage the antenna. Existing technologies make it difficult to achieve smooth deceleration and precise stopping.
Method used
By combining a variable gain control algorithm with other known control algorithms, the control strategy is switched according to the absolute value of the position loop error to limit the rate and magnitude of change of the target speed, and a smooth stop is achieved through the servo system driver.
Benefits of technology
It achieves shock-free and oscillation-free servo stopping, protects the antenna, simplifies the calculation process, and is suitable for stopping and precise positioning at any time.
