Simulink常用庫(kù)模塊介紹(Matlab2013a)

1、SIMULINK常用庫(kù)模塊介紹一、SIMULINK簡(jiǎn)介1、簡(jiǎn)介SIMULINK是一個(gè)對(duì)動(dòng)態(tài)系統(tǒng)（包括連續(xù)系統(tǒng)、離散系統(tǒng)和混合系統(tǒng)）進(jìn)行建模、仿真和綜合分析的集成軟件包，是MATLAB的一個(gè)附加組件，其特點(diǎn)是模塊化操作、易學(xué)易用，而且能夠使用MATLAB提供的豐富的仿真資源。在SIMULINK環(huán)境中，用戶不僅可以觀察現(xiàn)實(shí)世界中非線性因素和各種隨機(jī)因素對(duì)系統(tǒng)行為的影響，而且也可以在仿真進(jìn)程中改變感興趣的參數(shù)，實(shí)時(shí)地觀察系統(tǒng)行為的變化，因此已在許多領(lǐng)域，如通信、信號(hào)處理、DSP、電力、金融、生物系統(tǒng)等獲得重要應(yīng)用。對(duì)信息類專業(yè)的學(xué)生來(lái)說(shuō)，無(wú)論是學(xué)習(xí)專業(yè)課程或相關(guān)課程設(shè)計(jì)，還是在今后的工作中，SIMU
