| Abstract | Line-of-sight stabilized system, which can be used to isolate the vibration of the moving bed and the disturbance of environment, is the most important part of an electro-optical tracking system. The steady precision and robustness are the key issues of recent researches. In this paper, a novel control approach so called 2-Port Internal Model Control (2-PIMC) for line-of-sight stabilized system is proposed. By adding a parallel feedback control loop on the basis of Internal Model Control (IMC), the 2-PIMC method can improve precision while it also has strong robustness as the IMC. The robustness and the static error of 2-PIMC method were subsequently analyzed. Based on this novel method, Simulation and experiment are both carried out for a gyro stabilized platform of electro-optical tracking system. The experiments include a shaking table which can generate disturbance as the moving bed and a gyro stabilized platform which is mounted on the shaking table. The experimental result indicated that the gyro stabilized platform using 2-PIMC method is accurate and effective. Comparing with PI control, the following error and disturbance restraining error were both greatly improved at low-frequency and mid-frequency by the 2-PIMC method proposed. The improvement of precision is more than 10dB at 4Hz. In addition, the 2-PIMC method doesn't need any extra sensors for the platform and it's easy for parameters regulation. It can be concluded that the2-PIMC method is a new approach for the high-performance gyro stabilized platform and might have broad application prospect. © 2012 SPIE.; Line-of-sight stabilized system, which can be used to isolate the vibration of the moving bed and the disturbance of environment, is the most important part of an electro-optical tracking system.
