A PI Velocity Controller. Consider the PI velocity controller diagram to demonstrate the open-loop method. This form of PI control has two gains: KVI for the integral of velocity error and KVP, the loop-gain constant. The open and closed-loop Bode plots show their respective gains. In the Open-loop Bode plot, the gains are chosen to maximize the PM.
Yes. The Unity Ingot price can go up from 0.004034 USD to 0.004045 USD in one year.
The array is positioned as an SME and departmental array, with XtremIO (starting at $80-90K), VMAX and DSSD aimed at larger enterprise applications. Unity can perform up to three times faster than present VNX/VNxe arrays, delivering up to 300,000 IOPS. Burton said that, with the $18k starting price, it offered better performance than Pure's //M70 at half the price.
