永磁同步电机弱磁调速系统的仿真.在矢量控制的基础上进行改进，采用弱磁调速，可作为参考.(Permanent magnet synchronous motor speed control system simulation weakening in vector control on the basis of improved, using weak magnetic speed, can be used as reference.)

数据仿真，简单的回波信号时域滤波，动目标显示(echo simualtions, time filtering, GMTI)

说明：  function [ret,x0,str,ts,xts]=s3(t,x,u,flag) s3 is the M-file description of the SIMULINK system named s3. The block-diagram can be displayed by typing: s3. SYS=s3(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

航空飞行器6自由度动力学模型，用于飞行力学和飞机控制仿真(Aviation aircraft 6 DOF dynamics model for flight mechanics and aircraft control simulation)

A typical example of using the dSPACE system for electrical drives simulations is described in [9] and for wind energy conversion systems (WECS) in [10]. However, before the real-time implementation, the Control part has to be validated by simulation using a plant model. This model could be developed using either the Simulink transfer functions or the PLECS toolbox.
