Gyro stabilized pod disturbance suppression method based on fractional order disturbance observer

With the wide application of gyro stabilized pod systems in many neighborhoods, such as military and civilian, modem defense and industry requirements for the stability of gyro stabilized pod systems are also increasing. Aiming at the gyro stabilized pod system, a disturbance suppression method based on fractional-order disturbance observer is proposed. This method can reduce the impact of various disturbances on system stability. After the design of the improved fractional-order disturbance observer is completed, the simulation study is carried out. The results show that the improved fractional-order disturbance observer has faster response speed and stronger anti-interference ability than the traditional integer-order PID controller, so it can better meet the actual needs.
