摘要:线性常系数非齐次微分方程是LTI连续时间系统的数学模型。以输入信号为f(t)=e-2t的二阶微分方程为例,分析了两种不同形式的特解:yp(t)=p1te-2t+p2e-2t和yp(t)=te-2t,并从应用角度、物理意义等方面对二者进行了比较。
Liner invariant co-effect non-homogenous differential equation is the mathematical model of LTI continuous system. For the equation with such input as f( t ) = e^-2t, its particular solution has two patterns, which are yp ( t ) = te^-2t and yp(t)=te^-2t.It analyzed the two patterns of particular solutions in terms of application and physical meaning.
