Splet其特征方程为 s (s+2) (s+3)+K (s+1)=0 其特征方程可以化简为 1+K\frac {s+1} {s (s+2) (s+3)}=0 调用函数rlocus绘制根轨迹，必须要将特征方程写成这种形式，其中K为可变参数，变化范围为 0 到 +\infty 。 1. rlocus的输入实际上是一种特定形式的开环传递函数 % K (s+1) % The root locus for 1 + ------------ = 0 . % s (s+2) (s+3) % p= [1 1]; q= [1 5 6 0]; sys=tf … SpletFrom the second row s 2, 15 s 2 + K = 0. Putting the value of Kin the above equation, we get: 15 s 2 = -750. s 2 = -750/15. s 2 = -50. s = j7.071 and -j7.071. Both the point lies on the positive and negative imaginary axis. Step 7: There are no complex poles present in the given transfer function. Hence, the angle of departure is not required.
