With the increase of the speed and acceleration of the measured target, the rapid capture capability of the optoelectronic tracking servo system is increasingly required. The classical control method cannot fully meet the engineering requirements. This paper designs a proportional factor self-adjusting two-dimensional fuzzy controller and adds it to the optoelectronic tracking servo system. The simulation results show that the dynamic performance of the servo system has been greatly improved. In recent years, people have widely applied fuzzy control technology to various fields of production and life. It is favored by industry insiders for its independence from the precise mathematical model of the controlled object, good adaptability, good system robustness and easy implementation of non-overshoot control [1]. In particular, the two-dimensional fuzzy controller has attracted much attention for its relatively simple design and high control accuracy. Based on the classical control method, this paper adds a proportional factor self-adjusting two-dimensional fuzzy controller to form a servo control system model. By writing the S function of the M file to switch between the classical control method and the fuzzy controller, the simulation results show that the dynamic performance of the optoelectronic tracking servo system has been greatly improved.
