(4) torque control signal is calculated。
A. according to the voltage obtained in (1)And electric current, carry it into formula
WithIn obtainu s With, then the rotor velocity obtained through speed estimate/photoelectric encoder 11, then carry it into formulaWith
In, can be obtained by differential:
B. by the stator magnetic linkage in aAnd rotor fluxThe state equation being write as matrix is as follows:
C., the form that the electromagnetic torque of motor is expressed as stator magnetic linkage and rotor flux is as follows:
D. the control cycle is assumedT s It is sufficiently small, then obtain the state equation of discretization according to the matrix condition equation in b,t k+1The stator magnetic linkage in moment and rotor flux can be expressed as:
Which depictt k -t k+1Period is due to voltage vectoru sk The stator magnetic linkage caused by effectChange.With
Sample can derive electromagnetic torqueT s Discretization expression formula, if ignoringT s Quadratic term, can obtain following result:
E. the formula in above formula changes and obtainst k+1The torque variable quantity △ in momentT ek It is defined as:
By the torque variable quantity △ in above formulaT ek Three, middle the right is defined as △T ek1、△T ek2And △T ek3, then,t k+1Time
The torque carvedT e(k+1)It is represented by:
F. by above formula
With。
1) Section 1 torque variable quantity △T ek1It is the decay of the electromagnetic torque caused due to stator resistance consumed energy,
Therefore, it must be negative value.This witht k The torque in momentT ek It is directly proportional, with space voltage vectoru k And rotating speedUnrelated.
2) Section 2 torque variable quantity △T ek2Reflect space voltage vectoru k On torque change affect it can be as
In c, formula is such, is write as the form of vector product:
In formulaαFor space voltage vectoru sk And rotor fluxAngle, owing to electing zero vector as at space voltage vector
When, |u sk | it is 0, so Section 2 torque variable quantity △T ek2Being 0, it does not has yetαThe problem of angle.
3) Section 3 torque variable quantity △T ek3And rotating speed, be loaded with much relations, due to scalar product
Can represent:
Thus it is possible to it is as follows to derive further:
In formula,It it is vectorTo vectorAngle, when motor runningIt is less than 90oAcute angle, so △T ek3It it is negative value.

Amount △T ek3Composition, Section 2 torque variable quantity △T ek2Being zero, its torque variable quantity is as follows:
Due to △T ek1And △T ek3Total is negative value, therefore。
2) torque variable quantity △ when positive vector, anti-vector effectT ek +、△T ek -It is
, simply during positive vector effect, during anti-vector effectAnd zero vector
During effect, produced torque variable quantity is the same, is all negative, and its torque variable quantity is as follows:
Due to △T ek1And △T ek3Total is negative value, and therefore torque variable quantity during positive vector effect is as follows:
And during anti-vector effect, due to △T ek1、△T ek2And △T ek3Being negative value, torque during the most anti-vector effect becomes
Change amount is as follows:
Anti-vector is deducted positive vector, just obtains the relation between zero vector, positive vector, anti-vector three as follows:
H. the formula from above formula is it can be seen that work as regulation zero vector | △T ek 0| value become big time, positive vector makes electromagnetic torque
The amplitude risen | △T ek +| the least, whereas if regulation zero vector △T ek 0| value when diminishing, positive vector makes electromagnetism turn
The amplitude that square rises | △T ek +| the biggest.Therefore, " bigger zero vector effect | △T ek 0| " decapacitation strengthen readjustment electromagnetism turn
Outside the ability of square, it can also reduce the effect that positive vector makes electromagnetic torque rise, and kills two birds with one stone, and makes electromagnetic torque raising and lowering
Can preferably mate, the correct conditioning to electromagnetic torque has dual benefit.
I., when motor dynamically changes, motor wishes that electromagnetic torque has a greater change.And when entering steady-state operation,
Motor wishes that the change of electromagnetic torque is the least.According to this demand, can be at torque set-pointT e Delimit a district the most up and down
Territory, torque set-point as shown in Figure 2T e Scope in the most upper and lower two dotted lines, i.e.T e *±△T e ；And make following provisions:
