下列敘述為錯 請選出錯的地方並解釋其原因
1.It is possible to improve the tracking performance by an open-loop control
system.
2.As compare with a P control, a PI controller improves the steady state
error at the cost of asmaller damping ratio the bandwidth of the control
system is about the same.
3.in a feedback control system, if the plant has a pure integrator and
the controller also has a pure integrator , then the steady state error
tracking a parabola command is bound.
4.A D-term should be introduced into a PID controller when the response speed
is too slow.
有人會嗎@?@ 這幾題不太懂..
謝謝
