(The ultra-tightly coupled GPS/INS integrated navigation system latest research direction, it adopted the INS measured the carrier dynamic information auxiliary GPS receiver tracking loop to eliminate the satellite signal frequency due to the relative motion between the carrier and the satellite offset improve the receiver in high dynamic environment download wave tracking performance, but also can compress bandwidth, effectively enhance the anti-jamming performance of the receiver. Introduced GPS/INS ultra-tight coupling technology gives INS assisted GPS carrier tracking loop diagram and the corresponding mathematical model to analyze the impact of the INS assisted GPS tracking loop dynamic residues in a dynamic environment and the loop phase error, and model simulation, and analysis of simulation results verified. Simulation results show that the the residual secondary dynamic its resulting size of the error loop phase and jerk loop secondary is proportional to the time interval.)

本文在分析城市交通信号控制研究现状和交叉口交通信号控制原理、评价方
法的基础上,设计了单交叉口交通信号两级模糊控制系统。分级模糊控制能有效
减少模糊规则数,易于提取模糊规则,适合于交通状况复杂的城市交叉口交通信
号控制。但它存在难以由人工合理定义全部模糊隶属度函数的问题。为此本文进
一步采用遗传算法对两级模糊控制器中模糊隶属度函数进行优化。本文提出的方
法具有分级模糊控制的优点,同时可以使模糊隶属度的选取更为合理,获得更好
的控制效果。对一个四相位单交叉口,利用MATLAB在不同的交通条件下进行
了仿真,并利用交通仿真软件PARAMICS进行了可视化仿真。仿真结果表明该
