基于MATLAB的自動(dòng)控制系統(tǒng)時(shí)域頻域分析與仿真

摘 要

自動(dòng)控制系統(tǒng)就是在無(wú)人直接操作或干預(yù)的條件下，通過(guò)控制裝置使控制對(duì)象自動(dòng)的按照給定的規(guī)律運(yùn)行，使被控量按照給定的規(guī)律去變化的系統(tǒng)。在現(xiàn)代工業(yè)生產(chǎn)中，自動(dòng)控制系統(tǒng)已經(jīng)遍布每一個(gè)角落，對(duì)于線性時(shí)不變控制系統(tǒng)，可以通過(guò)時(shí)域、頻域分析法來(lái)分析系統(tǒng)的性能，但是對(duì)于多輸入多輸出的控制系統(tǒng)，時(shí)域、頻域分析已經(jīng)無(wú)能為力，鑒于這樣的控制系統(tǒng)，可以通過(guò)線性系統(tǒng)的狀態(tài)空間分析法來(lái)分析。本文針對(duì)自動(dòng)控制系統(tǒng)的設(shè)計(jì)很大程度上還依賴于實(shí)際系統(tǒng)的反復(fù)實(shí)驗(yàn)，結(jié)合具體的實(shí)例,介紹了利用先進(jìn)的MATLAB軟件對(duì)自動(dòng)控制系統(tǒng)進(jìn)行時(shí)域、頻域分析與仿真和線性系統(tǒng)狀態(tài)空間分析的方法，通過(guò)快速直觀的仿真和分析達(dá)到自動(dòng)控制系統(tǒng)的優(yōu)化。

ABSTRACT

Automatic control system makes object operate according to a certain law automatically to let the controlled quantity change by given law on the condition that nobody operate and control directly. Automatic control system exists every corner of the world in the modern industrialized production, which can analyze the performance of the system by time domain and frequency domain for the linear time-invariant control systems. However, to the system with multiple inputs and multiple outputs, the way to analyze through time domain and frequency domain can not do anything . Due to the control system, it can analyze through linear system state space. Due to this point that the design of automatic control system largely depends on repeated practice and modification, combined with the concrete example,this paper introduces the ways to analyze and simulate the time domain and frequency domain and linear system state space of automatic control system by advanced MATLAB,it can reach the optimal of automatic control system by direct and fast.

Key words: MATLAB Automatic control system Time domain Frequency
