The Application Research on Fuzzy PI Control Arithmetic of Photoelectric Stabilized Platform

摘要

Stabilized control is one of the key technologies of the photoelectric stabilization system. There is a conflict between overshot and transition time in the classical control theory, which can not satisfy the system dynamic performance. The stabilized control system mathematical model with great friction was set up. It was proved by the design and analysis that the normal and the adaptive fuzzy control system can not get a satisfied stable performance. So two kinds of fuzzy and PI multiplex control arithmetic, including fuzzy-PI and adaptive fuzzy PI, are provided and designed. Simulation and experiments show that the designed control systems can realize not only no overshot but also rapidity, and the performance are better than that of the classical control system. The work provides a new way for the stabilized control of photoelectric stabilized platform.
