Sampling time (T): is the time to sample the feedback val ue. In each s ampl ing peri od the controller

runs one time. The l onger the sampling t ime, the slower t he responding.

PID control discrepancy limit: t he allowa ble maximum discrepancy of PID system output va lue relative

t o the cl osed-loop as signed val ue. As shown in following diagram, within the discrepancy li mit, PID

controller stops adjustment. Properly set ting this function code can improve t he accuracy and st ability of

P ID syst em.

Feedback dis connected detecting val ue: t his detecting value is relati ve to the full range (100%).

The syst em detects the P ID feedback value all the ti me. When the fe edback value is less or equa l to the

feedback di sconnect ed detect ing val ue, t he syst em s tarts to time the dete ction. W hen the detecti ng time

exceeds the feedbac k di sconnect ed detect ing time, the system will s end an alert of feedba ck disconnecti ng

Proport ional gain (K p): det ermi nes the adjusting st rength of PID adjust or. The bigger the P, the bigger

the adjus ting st rength is. This parameter being 100 means that when the difference between the PID

fee dback value and the assi gned value is 100%, the adj usti ng ra nge of PID adjus tor t o the output frequency

command is the maxi mum frequency (ignore i ntegral acti on and derivative act ion).

Integrating ti me (Ti): determi nes t he speed at which PID adjustor performs integral regulat ion to the

discrepancy between the PID fe edback value and t he as signed val ue. The Ti is indicati ng the period of time

tha t integra l controll er (ignore proporti onal action and deri vative acti on), when the discrepancy between

the PID feedback value and the assigned va lue i s 100%, continuously regulates to make the regulating

amount t o reach the maxi mum frequency (F0. 047). The shorter the i ntegrating time, the stronger the

adj ust ing strength is.

Differenti al time (Td): det ermi nes the control ling st rength a t which PID adjust or performs adjus tment

to the variance ratio of discrepancy between the PID fee dback value and the a ssi gned value . The Td is

indicating t he period of time w ithin whi ch if the feedback val ue is changed 100%, t he regul ating amount

of integral controller is the maximum frequency (F 0.04) (i gnore proportional a ction and integral action).

The longe r the Td, the bigger t he controlling strength is.PID is the most popul arly used cont rol mode in

process control, with each part pl aying different rol e. Following simpl y introduces t he operational

principle and the controlling method:

Proport ion cont rol (P): when there is dis crepancy between feedback and the ass ignment, output t he

regul at ing amount in proporti on t o the discrepancy. If t he discrepancy is const ant,the regulating amount

keeps constant. Proport ion control can res ponse qui ckl y t o the feedback va ria ti on, but only using

proportion control is unabl e to perform noncorrespondi ng control . The bigger the proportional gain, the

faster the s ystem regulating speed, but being too bi g ma y cause os cillation. The control met hod is first to

set a long int egrating t ime and a zero differenti al t ime , and then run the s ystem only by using proportion

control. Change the assigned value, and watch the stable di screpa ncy (stea dy-stat e error) of feedback

signal and ass igned value. If the s te ady-sta te error is at the varying directi on of ass igne d value (for

instance , increa se the assigned value, the feedback va lue after the system i s steady is always less t han the

as signed value), continue to increase the proportional gai n, otherwi se decrease it.Repeat the above until

the steady-state error is relatively small (it is very difficult to do no steady-s ta te error).

Integral t ime (I): when there is a di screpancy between the feedback and assignment ,conti nuously

accumulate the output regulation amount. If the discrepancy still exists, continue to inc rease t he regulati on

amount until ther e is no di screpancy. Integral cont roller can effectivel y eliminate t he steady-state er ror.

Int egral controller being too strong can cause repeated overshooti ng, system unst able and up till oscillating.

The characteristi c of oscillation caused by too strong integral action is t hat t he feedba ck si gnal is swingi ng

up and down around the assigned value, and the amplitude of swing increases gradually til l the oscillation

happens. Normally the int egral time is adjust ed from big t o small, gradually regulate the integral time, and

watch the effec t, until the s ystem stable speed meet s re quirements.

Differenti al time (D): when the di screpancy between feedback and assi gnment varies,output a regulati on

amount i n proportion to the varianc e rat io of discrepancy. The regul ation amount is related to t he dire ct ion

and magnitude of disc repancy varia ti on, but irrel evant to the direction and va lue of the discrepancy itsel f.

The differential contr ol action i s t o perform the control according to the varying trend when the feedback

signal variation happens, and thereby t o restra in the feedback signal variation. It should be cauti on to us e

differenti al control ler as the differential control have a trend to magni fy the system i nter ference, especiall y

the high varyi ng frequency interference.
