最近学习自动控制原理,关于控制系统的一些,老师用布置了一些作业说要用matlab画,我试试python
1.control库:用来计算脉冲响应与阶跃响应
2.sympy:用以化简多项式为和的形式方便写参数
比如我们使用 sympy 来验证等式:x2+y2=(x+(2xy)1/2+y)(x−(2xy)1/2+y)
参照详细例子:
3.matplotlib 用以画图
分别是单位脉冲响应和单位节约响应的图像

round()函数用错了啊,你应该写成:
lb = round(fx*2.205, 2)
这样。
round(x[, n])
Return the floating point value x rounded to n digits after the decimal point. If n is omitted, it defaults to zero. Delegates to x.__round__(n).
For the built-in types supporting round(), values are rounded to the closest multiple of 10 to the power minus n; if two multiples are equally close, rounding is done toward the even choice (so, for example, both round(0.5) and round(-0.5) are 0, and round(1.5) is 2). The return value is an integer if called with one argument, otherwise of the same type as x.
