摘要
为了提高机载光电跟踪系统的控制性能,提出了一种模糊自适应PID控制算法。首先,针对机载光电跟踪控制系统的特点,建立了被控对象的模型。接着,对机载光电跟踪系统模糊PID控制器的设计进行了详细介绍。最后,利用经典PID控制、模糊控制、模糊PID控制3种算法对机载光电稳定跟踪系统进行仿真比较。仿真结果表明模糊PID控制算法较之前两种算法具有响应快、超调量小、抗干扰能力强、稳态性能好等优点,对机载光电跟踪系统具有较好的控制能力。
In order to improve the control performance of airborne electro-optical pointing and tracking systems,a based on fuzzy adaptive PID control system,is presented.Firstly,the characteristics of the systems are used to build the model of controlled object.Then the design on fuzzy adaptive PID controller of airborne electro-optical pointing and tracking systems are described in detail.Finally,using the classical PID control,fuzzy control,fuzzy adaptive PID control algorithm for three of the transfer function of the system compared to simulation.The simulation experiments are carried through contrast with former algorithms,and the results indicate that the algorithm is fast in response,low in overshot,robust in disturbance and the stability of it is good,so it has preferable control capability than former algorithms.
