In process control, the PID controller (also known as PID adjuster) carrying out controlling in the ratio (P) of deviation, integration (I) and differential (D) is a kind of automatic controller be most widely used.It is simple that it has principle, is easy to realize, and widely applicable, controling parameters is separate, the advantage such as selected fairly simple of parameter; And can prove in theory, for the typical subject of process control---the control object of " first-order lag+purely retarded " and " second-order lag+purely retarded ", PID controller is a kind of optimal control.PID Rule adjusting is a kind of effective ways that continuous system dynamic quality corrects, and its way of self-regulation is easy, structural change flexibly (PI, PD ...).
The selection of parameter:
1. proportionality coefficient P is on the impact of systematic function: proportionality coefficient strengthens, and makes being active in one's movements of system, and speed is accelerated, and steady-state error reduces; P is bigger than normal, and the number of oscillation is added, and regulating time lengthens; When P is too large, system can be tending towards unstable; P is too little, can make the slow in one's movements of system again.P can select negative, and this is mainly determined by the characteristic of actuator, transducer and control object.If the symbol of P select improper object measured value will from the set point of control objectives more and more away from, the symbol if there is such situation P just must negate.Simultaneously it should be noted that the P parameter of the PID controll block of the strategy controller of power control is the gain in PID control.
2. integral control I is on the impact of systematic function: integral action makes the stability of system decline, and I little (integral action is strong) can make system unstable, but can eliminate steady-state error, improves the control precision of system.
3. differential control D is on the impact of systematic function: the derivative action can improve dynamic characteristic, and when D is bigger than normal, overshoot is comparatively large, and regulating time is shorter; When D is less than normal, overshoot is also comparatively large, and regulating time is also longer; Only have D suitable, overshoot just can be made less, shorten regulating time.
Figure is as follows for summary simulation control of PID:
The discretization of 1.PID control law
PID controller is a kind of linear regulator, this adjuster is ratio (P), integration (I), the differential (D) of the control deviation c=r-y formed by the set-point r of system and real output value yy, controlled quentity controlled variable is formed, so be called for short PID controller by linear combination.Simulation control of PID rule in continuous control system is: u ( t ) = K P [ e ( t ) + 1 T I ∫ 0 t e ( t ) d t + T D d e ( t ) d t , In formula, u (t) is the output of controller above, and e (t) is the deviation of system specified rate and output variable, K pproportionality coefficient, T iintegration time constant, T dit is derivative time constant.Its respective transfer functions is:
G ( s ) = K p ( 1 + 1 T I s + T D s .
The effect of proportional controller, integral controller and differential regulator
(1) proportional controller: proportional controller is immediate reaction to deviation, deviation is once occur, adjuster produces control action immediately, and make output variable towards the direction change reducing deviation, the power of control action depends on Proportional coefficient K p.Although proportional controller is simple and quick, there is static difference in the control object being finite value for system responses.Strengthen Proportional coefficient K pcan static difference be reduced, but, K ptime excessive, the dynamic mass of system can be made to degenerate, cause output variable to vibrate, even cause closed-loop system unstable.
(2) proportional and integral controller: in order to eliminate the remaining static difference in proportion adjustment, integral adjustment can be added on the basis of proportion adjustment.Integral adjustment has accumulation composition, as long as deviation e is non-vanishing, it will affect controlled quentity controlled variable u by cumulative function, thus reduces deviation, until deviation is zero.If integration time constant T igreatly, integral action is weak, otherwise is strong.Increase T iby the process eliminating static difference that slows down, but can overshoot be reduced, improve stability.The cost introducing integration word joint is the rapidity of reduction system.
(3) proportional integral derivative controller: in order to accelerate control procedure, is necessary the moment occurring in deviation or change, controls by the trend of change of error, and deviation is eliminated in bud, the principle of differential adjustment that Here it is.Adding of the derivative action will contribute to reducing overshoot, overcome vibration, system is tended towards stability.
Because computer system is a kind of sampling control system, can only calculate controlled quentity controlled variable according to the deviate of sampling instant, therefore, utilize boundary rectangle method to carry out numerical integration, single order backward difference carries out numerical differentiation, when the sampling period is T, u i = K p [ e i + T T I Σ j = 0 i e j + T D T ( e i - e i - 1 ) . Meddlesome,
If the sampling period is enough little, this discrete approximation is quite accurate.U in above formula ifor full dose exports, the position that actuator's i-th sampling instant that it corresponds to controlled device should reach, therefore, i above formula is called that PID position type controls formula.
Can find out, when calculating by above formula, output valve is with all states are relevant in the past.What need when actuator is not the absolute figure of controlled quentity controlled variable, but during its increment, can derive formula below:
Δu i = u i - u i - 1 = K p [ e i - e i - 1 + T T I e i + T D T ( e i + 2 e i - 1 + e i - 2 ) ] , Above formula is called that incremental PID controls formula.
Incremental controls formula and has the following advantages:
(1) computer only exports controlling increment, i.e. the changing unit of actuator position, and thus misoperation impact is little.
(2) at the output u in i moment i, only need use the deviation in this moment, and previous moment, the deviation e in front two moment i-1, e i-2, and previous output valve u i-1, this has saved internal memory and computing time greatly.
(3) when carrying out manauto and switching, controlled quentity controlled variable is impacted little, can transition more smoothly; The computer of control procedure requires very strong real-time, during with microcomputer as digitial controller, due to the restriction of word length and arithmetic speed, necessary method must be adopted to accelerate computational speed.
Calculate control by PID, then regulated by PWM, output duty cycle.Temperature curve target temperature after control 180 degree of corresponding data points, as shown in Figure 9.
Figure 11 shows concrete software simulating step:
Step 1: code starts
Step 2: initialization MCU, AD, I/O port state, timer etc.
Step 3: can target setting temperature T by key user
Step 4: I the temperature T set by user is compared with the temperature T0 fed back, calculating error values, thus regulation output.If be greater than design temperature, step 5 stops exporting, otherwise step 6 opens unlatching PWM value according to PID calculating.
Step 5: go the temperature (such as, 10 milliseconds of monitorings once) of monitoring heater, according to circuit with certain period frequency, feedback device is connected in the middle of circuit, monitoring AD needs ceaselessly to power, but heater temperature can be caused to raise after power supply, measures inaccurate, therefore when needs, open metal-oxide-semiconductor Q2 to power, first back up the output valve in PWM before opening, carry out thermometric, Q2 is closed immediately, reduction PWM output valve after closing after thermometric.This situation testing time is short, general needs 30 microsecond thermometric, does not affect the temperature parameter of calandria but has and measure temperature very accurately.Calculate to measure while the temperature come outputs to step 7OLED display and also feed back to step 4 by step 8, carry out next step regulation output.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
