Abstract
During the flight, the airship load will be subject to various external disturbances, which will make the load camera unclear. To solve this problem, we have established a passive and vibration isolation platform, and used the characteristic model control method in the active vibration isolation system and the stable platform system. Firstly, the super magnetostrictive actuator is selected as the active control component to establish the active-passive integrated vibration isolation platform model. Then the internal relationship of the stable platform is analyzed, and the stepping motor control model of the stable platform is established. Finally, the characteristic modeling is carried out. The identified characteristic parameters are combined with the designed adaptive tracking controller, golden section controller and logic differential controller to control the active vibration isolator and the stable platform. The simulations show that the designed controller is effective.
