NS2入門指導 有助于初学者了解NS2，真的对新手有所帮助(Getting Started guide will help beginners understand the NS2, really help the novice)

永磁同步电动机调速系统由pmsm月吸逆变器、永磁同步电动机和机械负载三部分组成,每个部分都具有非线性特性和参数的不确定性。因为PWM逆变器死区的存在,在低速以及调制频率很高时,死区特性将会导致逆变器输出电压包含很大的谐波分量,使得电机转矩发生很大的 脉动,甚至导致系统的不稳定。有些学者采用变结构控制降低死区的影响,由于变结构控制本身具有抖振现象,这使得所设计的控制器在到达滑模平面之前很容易激起系统的未建模动态,导致系统无法克服逆变器死区的影响。 (A PMSM drive sysetm Consisst of ade-ac inverter,PMSM and sorne meehan iealload.All hteree eom Ponenst of hte syset maerhca racterizedb ymodel swhich aernon linear and eonati nullkllown Parameetrs. )

文针对 INS/ GPS舰船用组合导航系统进行 研究,为提高 INS 误差的修正精度,采用高精度 GPS姿态测量系统为 INS提供外部修正信息,以增 强系统的观测量.在对自适应卡尔曼滤波器分析的 基础上,提出了一种新的基于新息估计的自适应卡 尔曼滤波算法,以解决外部量测噪声出现不确定强 度变化问题.(Text for the INS/GPS navigation system for ships to study, to improve the accuracy of INS error correction, using high-precision GPS attitude measurement system for the INS amended to provide external information to enhance the system of observations. In the adaptive Kalman filter Based on the analysis, a new interest rate is estimated based on the new adaptive Kalman filter algorithm to solve the external uncertainties, the measurement noise intensity change.)
