Control algolithm
Simple, the realization easily of traditional PID controller algorithm structure is widely used in Direct Current Governor System, but is difficult to realize high accuracy and High-reliability Control.Fuzzy control is that it need not to set up Mathematical Modeling with fuzzy set, fuzzy language variable and the fuzzy logic inference a kind of Based Intelligent Control as control algolithm, is a kind of effective way that solves uncertain system.Fuzzy control is to utilize current control deviation; Dynamic characteristic in conjunction with controlled device; And the practical experience that is directed against detailed process, according to certain control requirement or target function, through the fuzzy rule reasoning; Three parameters to the PID controller are carried out online adjustment, so patent of the present invention is selected the adaptive Fuzzy PID Control algorithm in control procedure.
1. adaptive Fuzzy PID Control algorithm
Actual conditions according to system; Differentiation element is excessive to negative interaction from the electrical motor gearshift control procedure in the pid parameter; Cause the system responses process to brake in advance, prolonged the adjusting time, when motor quickens, causing bigger overshoot; So remove derivative action parameter here, only adopt the PI controller.
The design's fuzzy reasoning thought is: according to difference error amount e and error rate value △ e constantly, the parameter kp and the ki of PI controller carried out on-line tuning.It is the parameter correction part of conventional PI controller part and fuzzy control that its theory structure is made up of two parts.Theory diagram is shown in figure 17.
Can know by Figure 17 theory diagram, r (k) be k constantly from electric machine theory displacement input value, c (k) is a k actual measured value constantly, e (k) is a k error originated from input signal constantly, its PI controller form of expression that disperses:
Formula (1) is a position model PI control formula.In order to increase reliability, to the influence of system, adopt increment type PI control formula when reducing the DSP misoperation:
The control formula of final increment type PI controller:
Shown in figure 17, use fuzzy control rule, the input language variable of this fuzzy controller is error value E, error rate value △ E, the output language variable is the proportional gain factor kp and the integration gain factor ki of PI controller.Each linguistic variable is described below with the language value:
During E={ is negative big, negative, negative little, zero, little, in, big, △ E={ negative big, negative in, negative little, zero, little, in, big, ki={ zero, little, in, greatly }, ki={ is zero, little, in, greatly.Wherein in negative big, negative, negative little, zero, little, in, big brief note for NB, NM, NS, z, PS, PM, PB} quantizes to error value E and error rate △ E in the domain of [6,6].Likewise, { zero, little, in, big } brief note is { z, s, M, B}, and quantizing in the domain [0,6].
Practical operation experience and knowwhy in the system debug process, confirm the principle of adjusting of PI type Fuzzy parameter:
A, Error Absolute Value | e (K) | when big; In order to accelerate the response speed of system, and become and to cause that greatly the differential supersaturation makes control action exceed tolerance band because of beginning time error moment, should get bigger kp for avoiding; Prevent that for _ r integration is saturated simultaneously; Avoid system responses big overshoot to occur, should remove integral action, promptly get ki=0.
B, Error Absolute Value | e (k) | with | △ e (k) | during for median size, reduce and do not influence the response speed of system in order to make system responses overshoot, kp and ki can not get greatly, and should get less ki, and the kp value need be of moderate size.
C, Error Absolute Value | e (k) | hour, have good steady-state behaviour, should increase the value of kp and ki, near set point, occur vibrating for fear of system simultaneously, and consider the interference free performance of system, select suitable kp value in order to make system.
The method of measurement that adopts in the patent control procedure of the present invention is following:
Method 1: in patent of the present invention, force value realizes measuring through high accuracy 24 bit A/D converters, and its method of measurement is:
Wherein F is tested force value; X is the AD converter number of significant digit;
for pressure sensor output maximum pressure value,
is AD converter output digital value.
In patent of the present invention; Choosing pressure sensor output maximum pressure value is 100kgf; AD converter is 20 AD of high accuracy; Can be drawn by above condition, crimping Systems Theory pressure measxurement minimum resolution is
Method 2: the selective light photoelectric coder is as the dimensional measurement transducer in patent of the present invention, and the photoelectric encoder that this patent is selected is the incremental encoder of 1000 pulses of every circle output.Because it is 4mm (displacement that screw mandrel whenever rotates a circle is 4mm) that mechanical device is selected the screw mandrel helical pitch, screw mandrel rotates a circle and exports 1000 pulses.There are 4 edges in each slit: two passages of TMS320F2812PGFQ orthogonal coding circuit respectively have a rising edge and a trailing edge; That is to say; Screw mandrel whenever rotates a circle; TMS320F2812PGFQ orthogonal coding electric circuit inspection to 4000 edge, TMS320F2812PGFQ leaves detected edge number in the internal counter in.It is 0.001mm/ that the above least displacement resolution that draws the electric control gear energy measurement is arranged.
The accurate compression bonding apparatus of realization visual intelligent provided by the present invention, this measurement mechanism part has: compositions such as supporting bracket 1, supporting bracket, supporting bracket 3, lock shaft, crimping frock, depression bar axle sleeve, servomotor, reductor, liquid crystal display, keyboard, control board, base, photoelectric encoder, moving slider, back high accuracy line slide rail, high accuracy roller bearing screw mandrel, preceding high accuracy line slide rail, accurate deep groove ball bearing, accurate linear bearing, depression bar, shaft coupling, supporting seat, pressure sensor, accurate linear bearing, shell, anticlockwise support arm.
