Re: [問題] 求matlab解答,急~已回收
※ 引述《avgpk ((囧mmmmmmmmmmmmmmmm))》之銘言：
: Consider a unity feedback system with transfer function G(s)=K/s(s+10)(s+14)
: It is desired to compensate the system so as to meet the following specific-
: ations.
先調整準度：
Kv=(s趨近於零)sG(s)=K/140, Ess=1/Kv=0.1 -->K=1400
有很多種補償器的功用，都可以達到a跟b的要求@@
看老師教到哪一種@@
: (a) percent overshoot< 5% for a step input.
: (b) Settling time < 3 sec
: (c) Steady state error < 0.1 for a ramp input
: Use root locus and Bode diagram, respectively.
設計方面感覺像是自動控制的問題
如果是matlab的話，可以使用Benjamin C. Kuo寫的Automatic Control Systems
書裡面的光碟，ACSYS軟體，希望對你有幫助@@
