这是2dof（pi-逆前馈加pid反馈），单纯pid反馈，单纯pi模型逆前馈对应的仿真结果。 其中系统模型采用前面根据pi模型与n4sid算法结合得到的综合模型。(This is 2 dof (PI- inverse feedforward pid feedback), pure pid feedback, pure PI inverse model feed-forward corresponding simulation results. In front of the system model using models based on PI and n4sid algorithm combined with integrated model.)

广义互相关时延估计，瑞利限广义互相关时延估计，瑞利限广义互相关时延估计，瑞利限(Generalized cross-correlation delay estimation, generalized Rayleigh limit cross-correlation delay estimation, generalized Rayleigh limit cross-correlation delay estimation, the Rayleigh limit)

matlab实现的一个交互式多模型算法程序，可以用于目标跟踪领域。(matlab implementation of an interactive multiple model algorithm program can be used for target tracking.)
