标题[理工] [控制]-交大94-电机-根轨迹
时间Mon Jan 11 11:45:36 2010
Find the center of asymptotes for the 180°root locus in terms of p and z
and determine the condition that the closed-loop system is stable as the
gain K is large enough.
s + z 250
开路转移函数为 K(----- )(---------)
s + p s^2 - 100
180°root locus是什麽意思? 跟一般根轨迹不一样吗@@?
-p + z
他解答写θ_A = ------ < 0 ∴ p > z
2
为甚麽渐近线和实轴交点一定要小於0阿?
