Research of Three Axis Tracking and Pointing Platform Servo Control System

The design of stabilization and tracking loop controllers of tracking and pointing platform is considered in the paper. This design is based on mathematical model that the coupling among three-axis frame is considered. An state feedback H-infinite controller based on linear matrix inequality (LMI) is designed for stabilization loop of tracking and pointing platform. The observed structure decomposition for system is done and H-infinite filter is designed. Variable universe fuzzy PID controller for tracking loop is designed and some improvement is done. The simulation results show that the designed controllers have good performance.
