In modern warfare, the status of infrared-guided missiles is increasing, and the most countries in the world attach great importance to the development of infrared-guided missiles. The performance of the seeker gyro, as a key component of missile guidance control, has a decisive influence on the operational capability of missiles. In this paper, we analyze and study the suspension, spin up and speed stabilization control problems in the gyroscopic tracking system of a certain type of seeker, and propose a new control method to realize the highly reliable and fast spin up control of the seeker gyro and complete the test verification. The experimental results show that the fast spin up control design of this paper can ensure the high reliability and shorten the start-up time of the seeker at the same time, which can effectively improve the operational performance of the missile.
