: ※ 引述《chuangs (该来的终究会来)》之铭言：
: 分别解释P、I、D控制器，不要用数学(转移函数)，用物理现象解释
: 请问要怎麽解释？
: D和I控制器适用微分和积分的观念去解释吗？
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 :)
