Research on Adaptive Kalman Filter Variable Structure Controller for Missile Rudder System

Inhalt:
The steering gear controller is a key part of the steering gear control system. It outputs the driving motor signal according to the rudder deflection angle command signal and the steering gear system feedback signal, so that the steering gear can deflect according to the specified angle. For the rudder system, the Kalman filter variable structure controller can effectively optimally filter the input signal with external random interference. However, Kalman filtering also has its limitations. During the flight of a missile in a complex environment, it cannot accurately predict the external noise to the steering gear system, so the system cannot achieve optimal filtering. In this paper, an adaptive Kalman filter variable structure controller is designed on the basis of the Kalman filter variable structure controller, and its advantages and disadvantages are compared and analyzed.
