针对经典稳定控制理论存在超调与快速性之间难以调和的矛盾,建立了稳定控制系统数学模型,采用自适应模糊实现控制的快速性,用PI保证系统的稳态精度,以误差为模糊控制的输入,设计一种实用的自适应模糊和PI复合控制系统,并在基于VxWorks实时操作系统的数字平台上得以实现.仿真和试验表明:设计的新型自适应模糊PI复合控制系统超调量为0,调节时间约8 ms,带宽约29 Hz.

Control method of adaptive fuzzy and PI for photoelectric stabilization based on real-time OS

The stabilization control technology is one of the core technologies of the photoelectric stabilizing and aiming products. It is difficult for classical control theory to deal with the conflict between the overshot and rapidity, and to get satisfied dynamic performance. The system mathematical model was set up, and an adaptive fuzzy and PI compound controller was designed, which was realized on a digital platform based on the VxWorks OS. The simulation and experiment show that the system can realize the goals of zero overshot and rapidity with the designed controller. The system bandwidth was enhanced, which would favor the improvement of stabilization accuracy. The research provided a new stabilization control method for congeneric products.
