Description: 随着计算机技术与通信技术日新月异的发展，无线局域网在个人和商业计算机 领域日益流行起来。随着用户的要求不断提高，无线局域网向更高频率、更宽带宽 的方向发展。IEEE802.11a/b/g是现在市场占有较大优势的无线协议标准，但是也越 来越不能满足无线局域网通讯的要求。IEEE802.11n标准是对802.11g的一场更新换 代。802.11n可以提供更高的传输速率，更广的覆盖范围，兼容802.11a/b/g。随着 频率的提高和带宽的增加还有协议的日益复杂性，射频前端的设计越来越不能脱离 数字基带的要求。计算机辅助分析和综合的工具还不能满足数字基带与射频部分的 联合仿真。所以，基于一定协议的射频电路的系统级设计的建模与仿真问题还有待 于开发。本论文基于最新无线局域网的IEEE802.11n草案标准，使用Matlab/Simulink 与MathCAD软件对射频前端电路进行建模和仿真，并建立数字基带联合仿真环境。

Description: This simulink model simulates the damped driven pendulum, showing it s chaotic motion.
theta = angle of pendulum
omega = (d/dt)theta = angular velocity
Gamma(t) = gcos(phi) = Force
omega_d = (d/dt) phi
Gamma(t) = (d/dt)omega + omega/Q + sin(theta)
Play with the initial conditions (omega_0, theta_0, phi_0 = omega(t=0), theta(t=0), phi(t=0)) and the system parameters (g, Q, omega_d) and the solver parameters/method.
Chaos can be seen for Q=2, omega_d=w/3.
The program outputs to Matlab time, theta(time) & omega(time).
Plot the phase space via:
plot(mod(theta+pi, 2*pi)-pi, omega, . )
Plot the Poincare sections using:
t_P = (0:2*pi/omega_d:max(time))
plot(mod(spline(time, theta+pi, t_P), 2*pi)-pi, spline(time, omega, t_P), . )

Description: A collection of functions for programatically manipulating the structure and connectivity of Simulink models. In Simulink, models can be altered using a collection of built-in function calls (e.g. add_block, add_line) and by modifying block parameters (using set and set_param). Maniuplating these parameters directly is tedious and requires a great deal of error-checking code. These functions make a variety of tasks--adding or removing a block, connecting or disconnecting pairs of blocks, modifying block positions and sizes, etc.--to accomplish via simple function calls. Generally, the most common use of these functions is in a masked subsystem initialization callback. For example, if you design a masked subsystem which has an adjustable number of inputs, when the user changes the number of inputs required, the initialization callback will need to create additional or destroy extra block inports and connect them to their desired destinations within the subsystem.

实用的永磁同步电动机驱动系统-Electromechanical sensors are commonly used to obtain rotor position/speed for high-performance control of interior permanent magnet synchronous machines (IPMSMs) in
vehicle systems. However, the use of these sensors increases the cost, size, weight, wiring complexity and reduces the mechanical robustness of IPMSM drive systems. These issues, together with
some practical requirements, e.g., wide speed range, extreme
environment temperature, and adverse loading conditions, make a sensorless control scheme desirable. This paper proposes an extended back electromotive force (EMF)-based sliding mode
rotor position observer for sensorless vector control of IPMSMs.
Based on filter characteristics, a robust compensation algorithm is developed to improve the performance of the sliding-mode observer (SMO). Multistage-filter and dual-filter schemes are designed to further improve the steady-state and transient performance, respectively, of the compensation algorithms. The proposed SMO and c
