摘    要:基于Magill的Kalman撼波器池结构,设计了使用遗传算法的自适应Kalman滤波器,给出了离线和在线两种实现方案.离线方案以辨识滤波参数为主要目的,进而可以对状态进行较准确的事后估计;在线方案以实时地对状态进行估计为目的.对滤波参数寻优使用具有良好性能的浮点数编码遗传算法,该算法与二进制编码遗传算法相比收敛速度更快、搜索全局最优的能力更强.仿真结果验证了所提出的自适应Kalman滤波器的有效性.

关 键 词:遗传算法  自适应Kalman滤波器  自动控制  滤波参数  编码  目标函数  滤波器池  估计误差

Abstract:Adaptive Kalman filter with genetic algorithm was designed on the configuration of Magill's Kalman filter bank with. Two realization schemes including off-line and on-line given. The off-line scheme aims primarily at identifying filtering parameters, and the postmortem estimation of states can be obtained more accurately while. The on-line scheme aims at real-time estimation of the states. A well-performed float-coded genetic algorithm was used to optimize the filtering parameters. In comparison with the binary-coded genetic algorithm, this algorithom has higher convergence speed and greater ability of finding global optimum. The efficiency of the proposed adaptive Kalman filter has been verified through simulation.
Keywords:adaptive Kalman filter  filter bank  filering parameter  genetic algorithm
