: ※ 引述《chuangs (該來的終究會來)》之銘言:
: 分別解釋P、I、D控制器,不要用數學(轉移函數),用物理現象解釋
: 請問要怎麼解釋?
: D和I控制器適用微分和積分的觀念去解釋嗎?
Proportional control (P) can reduce error responses to disturbances but
remain nonzero steady-state error to constant input.
Proportional to integral of error (I) can eliminate steady-state error
but get worse in dynamic response.
Proportional to derivative of error (D) can improve dynamic response but
may make system unstable.
This is the intoduction of PID controller in Franklin's book,
may this have some effort to your problem :)

2F:推 iammonkey:P放大比例 I 累績誤差 D 預期性控制 參考一下 05/04 00:02
