If | e (k) |<M2, error input quantity now is in the direction change towards increase, but error input quantity is absolute Value is little, it may be considered that implements general control action, to reduce error input quantity, it is subtracted towards the absolute value of error input quantity Small direction change, current control amount is:
U (k)=u (k-1)+kp[e(k)-e(k-1)]+kie(k)+kd[e(k)-2e(k-1)+e(k-2)];
Or, u (k)=u (k-1)+kpΔe(k)+kie(k)+kdΔ2e(k)。
(3) in e (k) Δs e (k)<0、e(k)Δe(k-1)>0 or in the case of e (k)=0, the absolute value of error input quantity Towards the direction change for reducing, or poised state is reached.Now, it is contemplated that take holding controller to export constant, electric current Controlled quentity controlled variable is still:
U (k)=u (k-1)
(4) in e (k) Δs e (k)<0, Δ e (k) Δ e (k-1)<In the case of 0, error input quantity is in extreme value state, such as Really the absolute value of this time error input quantity is larger, i.e. | e (k) |>M2, it is contemplated that implement stronger control action;If this mistiming The absolute value of difference input quantity is smaller, i.e. | e (k) |<M2, it is contemplated that implement weaker control action, then current control amount is:
U (k)=u (k-1)+k1kpem(k) |e(k)|≥M2
U (k)=u (k-1)+k2kpem(k) |e(k)|<M2
In formula, k2It is rejection coefficient, 0<k2<1;emK () is k-th extreme value of error e, emK () is by each sampling above Cycle obtains after data are compared and obtains.
(5) exist | e (k) |<In the case of ε, the absolute value of error input quantity very little now adds integral element, subtracts Lack steady-state error, current control amount is:
In formula, ε is the desired error precision value for obtaining, and can be arbitrarily small real number,It is to error Integral term.
It should be noted that:Pid parameter value k under various situations mentioned abovep、ki、kdIt is different, the present embodiment In, can be by kpInitial value be set between 30-70%, kiInitial value be set between 24s-180s, kdInitial value setting Between 3-180s, parameter designing then is carried out using test of many times debugging, adjust the value of each parameter, finally obtain each feelings More satisfactory parameter value under shape.
