Four quadrant running.Current feedback detection adds amplifier using the mOhm grade smart power resistance of low cost to realize.Pass through
It is known that the size of current of current time motor after the ADC conversion of TMS320F2812.
In order to allow the more stable quickly follow current reference instruction of current of electric, electric current loop uses pi regulator.Speed ring
Output error E, error E output voltage control after PI is controlled after output valve V is instructed compared with current of electric I as current reference
The generation of quality management PWM, the size of PWM full-bridge drive control current of electric and direction, it is big come the torque for controlling motor with this
It is small to achieve the purpose that control revolving speed, position.The computer implemented formula of electric current loop number PI control is as follows:
E (k)=V (k)-I (k) (15)
U (k)=Kp×E(k)+Ki×∑E(k) (16)
Wherein V (k) is speed ring output valve, in this as current reference instruction input；I (k) is motor current value；K is
Sampling sequence number； KpIt is constant for proportionality coefficient；KiIt is constant for integral coefficient；From formula (15) and (16) as can be seen that U
(k) value is related with sampling number, if sampling number is more, calculates also more.It is normally applied and seeks Δ U (k):
U (k)=U (k-1)+Δ U (k) (18)
It is from formula (17) it is known that only related with current and last time sampled point, simplify calculating.
(2) speed ring
For better tracking velocity reference instruction, speed ring also uses pi regulator, the same electric current loop of PI controller architecture
Identical, the computer implemented formula of speed ring number PI control is as follows:
E (k)=P (k)-V (k) (19)

Up to formula, only E (k) calculation formula is different.
(3) position ring
Position control ring is the key link realizing motor position and being accurately positioned, to prevent from noise occur when motor is static,
There is no integrator in this link, increasing derivation damp link prevents system oscillation.The pid parameter of motor control is passed by serial ports
Enter, real-time must adjust to reach best control performance is carried out by serial ports.
The computer of position ring number PD control realizes that formula is as follows:
E (k)=CP (k)-EP (k) (21)

CP (k) is position command；EP (k) is motor feedback position value；KpIt is constant, K for proportionality coefficientiFor integration system
Number, is constant；Δ P (k) is first sought here in order to simplify operation,
Δ P (k)=Kp×(E(k)-E(k-1))+Kd×(E(k)-2×E(k-1)+E(k-2)) (23)
P (k)=Δ P (k)+P (k-1) (24).
