英文摘要	Classic servo systems typically use Dual Closed-loop Feedback (DCF) control as the tracking control method. When the system tracks the large position deviation signal, the DCF often has too much overshoot problem due to the integral failure (Windup), which is unacceptable for some precision equipment. Based on this, this paper proposes a control method for large position deviation signals (CLPS) by adding transition signals based on DCF, in which the transition signal is used to smooth the input and makes the jumping large position deviation signal become to a slowly changing one. And the transition signal is time optimal, this reduces the settling time while decreasing the overshoot. Finally, the control algorithm is verified in the electro-optical tracking (EOT) system and the experimental results show that the fast and smoothness of the system reach the expected goal, and the control method has obvious tracking effect improvement compared with the DCF. © 2019 IEEE.
