摘要	A dual mode control technology in combination of fuzzy control method with lag-lead compensation method was introduced to improve the response speed, anti-jamming performance and to reduce the overshoot of an electro-optical tracking system. The operation principles of fuzzy control method and lag-lead compensation method were introduced respectively. Based on the advantages of two methods mentioned above, the dual mode control system was designed. Then the MATLAB was used to perform the simulation experiments for the dual mode control system and corresponding actual experimental verification. The simulation results show that dual mode control technology reduces the overshoot of the system, improves the response speed of the system effectively and has a much better capability in anti-jamming as compared with the lag-lead compensation method. Furthermore, the actual experiment of the dual mode control technology was performed on an electro-optical tracking platform, the experiments by 180 step for azimuth subsystem and 60 step for elevation subsystem were carried out. The results show that the overshoots of both azimuth and elevation subsystems reach 0%, meanwhile their adjusting time and precision of steady state are improved. It concludes that the dual mode control method is characterized by faster responding speeds, small overshoot and higher capability in anti-jamming. 2016, Science Press. All right reserved.
