(1) Description: Adjust the PID parameters; Kp is the proportional coefficient, Ki is the integral coefficient, and Kd is the
differential coefficient.
(2) Type: Settings block
(3) Example: EP CORE’s line follow
Modify parameters of Kp, Ki, and Kd to optimize the closed-loop control system.
Note:
Proportional
Control
(P Control)
Amplifty or weaken the error signal.
Proportional coefficient determines
the strength of control.
The larger the proportional coefficient, the
more responsive the system becomes. But
may oscillate and destabilize the system if
the coefficient is too large.
Cannot eliminate the
steady-state error of the
system, lowering the
relative stability of the
system.
Integral
Control
(I Control)
Affect controller output with error
accumulation, and reduce deviation
with negative feedback of the
system.
It is related to the existence period of the
error signal. As long as there is enough time,
the integral control can eliminate the
steady-state error.
Fail to overcome the effects
of interference in a timely
manner.
