Nie można tego zrobić, ale to jest to, co jest w tym przypadku najważniejsze.
Derivative Action
Te derywatywy action przewiduje future process behavor based on thee current rate of change. It providees a damping effect, reducing overshoot and oscillations. The derywatyve action is contribul tam te rate of change of thee process variable.
Te matematyczne wyrażenie jest tym, że te pochodne action is:
(d) * (d / dt) e (t) (t) (t) (t) (1) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n) (n (n) (n (n) (n) (n) (n) (n) (n (n) (n) (n) (n (n) (n) (n) (n) (n (n) (n) (n) (n) (n (n (n)
where message 1; individence 1; individence 1; individence 1; individence 1; individence 1; individence 3; individence 3; individence 3; e (t) individence 1; individence 1; individence 1; individence 3; individence 3; individence 3; is the error signal. In discite systems, the deriative is approxiated using dividividences between successive error values.
Integral Action
Te integral action akumulates thee error over time, helping eliminate steady-state errors. It additions theme control output based on thee total accumulated error, ensuring the process variable reaches thee setpoint.
Te matematyczne wyrażenie for thee integral action is:
Xi1; Xi1; FLT: 0 Xi3; Xi3; I (t) = Ki * Xie (t) dt Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
were behind 1; index1; FLT: 0 behind 3; Ki behind 1; index1; FLT: 1 behind 3; index3; is the integral gain. In disre systems, the integral is calculated by y summing the error over diste time intervals.
Calculating Actions
Obliczanie derywatywy i działania integralne involves selecting appropriate gains andundering thee process dynamics. Proper tuning ensures the control systems responds procitately with out excessive oscillations our sleegishness.
