MATLAB软件在系统稳定性分析与仿真中的应用

系统的稳定性是系统实现其功能的前提,因此,对系统进行稳定性判断就显得很有必要.判断系统的稳定性可以从系统的线性模型出发,导出系统的系统函数,利用MATLAB软件对系统函数的极点分布情况和冲击响应的模式进行分析,并对系统进行建模仿真,得到系统的极点分布图和冲击响应的模式图,在此基础上,对系统的极点分布图和冲击响应的模式进行分析,根据系统稳定的条件,判断系统是否稳定.

The Application of Matlab in the System Stability Analysis and Simulation

The stability of a system is the precondition to realize the function of the system. So,it is necessary to estimate the stability of a system. It can start from linear model of the system,and then derive the system function. MATLAB can analyze the distribution of poles in system function and mode of impulse response. Modeling Simulation of system can get the distribution map of poles in system function and mode map of impulse response. Based on these analyses and depending on conditions of system stability,it can be determined whether the system is stable or not.
